Best wireless mouse I've owned to date.
I have owned a few wireless mice over the years, most recently an older Razer Naga, with mixed results. The battery life on most “gaming” mice I’ve used before has been awful, and as I frequently forget to put mice back on their docks after 25 years of using wired mice, most of the time I’d return to the mouse only to find it dead, plug it back into the cable, and just leave it in wired mode 98% of the time. But so far, this mouse has never once died on me, even with the lighting left on, and even when I forget it. The sleep function works, and with its surprisingly good active battery life, it is never dropped below 30% power. The sensitivity is freakishly high, and I’m not really sure why anyone would need 20,000 DPI but it’s there if you have a use case for it. I like that it has the ability to adjust the tension on the scroll wheel and can range from extremely smooth scrolling to snapping steps depending on preference. Probably my favorite feature thus far is the optional “clutch” button on the side, which I remapped to F13 and use now as my Push-To-Talk key in discord. I have always liked having PTT as mouse 4 or 5, but it is nice to now have a “mouse 6” of sorts that is well positioned and not otherwise dedicated to something else like window navigation. Despite the fact I am giving this mouse a 5/5, it has not been 100% without issue. The wireless would drop out frequently at first, and the mouse would stop responding completely until it was plugged in, or the hub was unplugged and replugged, at which point it would stop working again within minutes or hours. Other users suggested this was possibly a problem with the USB port going into “sleep” mode, so I went and set every port I could find to never shut off, but to no avail. However, after trying a couple different USB ports, I found one that seemingly did not have this problem at all, and it has been fine ever since. As others have experienced this issue with this mouse, it’s worth keeping in mind that if you experience this problem, it might not actually be the mouse’s fault, even if it seems to be especially vulnerable to it. Overall, I am quite happy with this mouse. It’s on the expensive end to be sure, but it’s the first wireless “gaming mouse” I’ve used that actually functions as a wireless mouse for me.

Great Modern Mouse
I have been switching between mice for a while now, and steered clear of wireless mice since my last experience with an older Logitech mouse back in 2014. I was quite happy when I found Mionix, and favoured the Naos 7000 as my daily driver for years until the cable broke. I saw the Castor, and figured that would be a sidestep. It lacked the ergonomics, but had the build quality I loved. At the time, I thought that Mionix with its "perfect sensor" and premium feeling rubberized coating was as high-end as you can get, all without the fancy gamer stuff thrown in. When it came to Razer, I never really thought I would buy another one of their products. I had terrible experiences in the past, with my Tiamat headphones quite literally falling apart from standard use with both the cable fraying and the control box splitting open and exposing the delicate wires inside. Whenever I tested their keyboards during my early mech days around 2015, I thought they lacked the build quality of even cheaper mechs on the market. Many reviews online supported my thoughts that Razer had terrible quality assurance, so I resolved never to buy another of their products ever again. Apparently, that all changed in the past few years. In comes the Razer Basilisk, a very premium feeling wireless mouse that lives up to its claims. Whether I am using it in wireless or wired mode, there is absolutely no input lag and the movements feel silky smooth. If I had any complaint at all, it would be that the 100 hour claim feels a bit overstated. Yes, it will last you all day and the charging time itself is quick. However, after only 6 hours of use from 100% I did notice in Synapse the mouse was already around 74% operating at around 7000DPI with standard polling rates. Beyond that however, the mouse itself feels spectacular. I had previously been using a gel pad for my wrist with the Mionix mice, but it feels entirely unnecessary with the Basilisk. It feels extremely good in the hand, and while a similarly priced Logitech may feel like light plastic, the Basilisk manages to replicate the feeling I got from the Naos or the Castor without the heavy application of rubber. The scroll wheel adjustment is a fantastic feature, and though I wish there were infinite scroll I still enjoy the ability to set the tactility of the clicks or to have no tactile feedback at all. Overall, very amazing mouse.

I've bought this mouse not because my previous was gone/damaged/vaporated, but because the previous Razer Basilisk Ultimate is 5 years old and I've used it a lot :DDD No cons at all, just maybe the battery capacity becomes less after 5 years :D In general - perfect mouse.

Mi Logitech G502 le comenzaron a fallar los botones así que elegí este modelo como sucesor. El G502 tiene piezas metálicas para agregar al gusto y personalizar el peso y distribución del mismo, en teoría es genial pero en la practica sin tener conocimiento sobre como hacer el ajuste es algo molesto, el Razer ya viene con un peso predeterminado el cual es el ideal. Mientras que el Razer tiene un ajuste manual sobre la resistencia de la rueda al girar, el punto mas ligero no es lo suficientemente ligero para mi gusto, en cambio el G502 tiene un botón que ajusta una resistencia "normal" cercana a la mas ligera del Razer y hace el cambio a ninguna resistencia lo cual permite que la rueda gire por inercia lo cual es genial al navegar en paginas por internet, es un punto en el cual en mi opinión le gana al Razer y esperaba que también lo tuviera. El cable USB que incluye es muy suave , muy cómodo si no vas a usar el dock y vas a conectarlo directo al mouse. El dock es genial y muy útil cuando te acostumbras a colocarlo para cargar a la primera. La iluminación es genial, el software tiene muchas opciones, es tedioso si no te gusta meterte demasiado a los ajustes, pero genial si prefieres personalizar lo mas posible tus periféricos. Si tuviera que mencionar algún "contra" del dispositivo solo mencionaría dos. -El ajuste de la resistencia de la rueda debería tener la opción de cero resistencia. -La batería no dura mucho, si usas el ajuste de la iluminación a la mitad (intensidad), en ese nivel podría durar un turno de trabajo, la carga es relativamente rápida pero seria genial mas capacidad de parte de la batería. Si vienen de algún mouse mas económico es una buena opción, pero sugiero esperar a la temporada de promociones para conseguirlo a precio atractivo y vendido por Amazon, también sugiero invertir en una garantía extendida por si las dudas. Actualización: Debido a que es mi primer mouse de esta gama inalámbrico y con un dock hay un detalle que me atrapo desprevenido y puede que les sirva. A dos meses de estarlo usando continuamente empecé a notar que tardaba en habilitarse después de haberse apagado para ahorrar energía y al montarlo en el dock a veces no lo ponía en carga y solo se quedaba con el patrón de luces. Al parecer la memoria del mouse se satura y comienza a ciclarse o congelarse al hacer cambio de acciones (pasar de hibernación a activo o de estar en uso a cargando, incluso note que la batería le duraba menos) lo cual se soluciona apagando y volviendo a encender el mouse desde el switch en la parte de abajo , después de esto reacciona igual que el primer día de uso, ahora lo apago cada que me voy a dormir y lo dejo en su dock cargando.

I needed a replacement for my G502 proteus core which i've had since 2015 or so, I really needed a mouse with a similar button layout, specifically a thumb button as well since I use that alot for VOIP push to talk and I'm way too used to it. I have a g502 hero mouse too but the double clicking issue with logi has gone beyond belief at this point and I just can't risk buying another set of mice like it (I already RMA'd the hero mouse once) just failing with switches over and over, it wastes my time far too much. Granted, my old proteus core is still kicking but I needed another mouse for work as well. The basilisk so far, first day of use, these are my impressions: **The GOOD GOOD**: -Small -Lightweight (compared to g502) -Resistance levels are adjustable for the scroll wheel -Razer software allows on board memory usage as well, I don't really have complaints with Synapse. -Thumb button is fantastic, feels fantastic -Side buttons feel alright, I do like the feel of the G502 better but they're fine. ***The not so good good*** - Seems like the battery life might not be 100hrs as advertised, 1.5 hours of use drained almost 12% already though it is not in low power mode. This might not be ideal for long extended 15-18 hour gaming sessions which I really don't do anymore unless I'm on holidays or something, I'm testing the low power mode and will report again eventually. -no other issues observed yet. Overall: Well, I can't really complain, it's wireless, it feels good, it's responsive even in low power mode right now, the dock is magnetic so it's extremely easy to just latch on and leave (very big bonus). The thumb button is removable but it also feels fantastic as button concept is far superior to what the G502 had. Time will tell if the mouse holds up to my old logitech treasure, my initial experience with a Razer Naga over 10 years ago was absolutely traumatizing, the thing maybe lasted 6 months between double clicking issues and eventually the sensor just dying on me. This new Basilisk + the Synapse software seem to have redeemed my praise for Razer, they've come a long way but again, time will tell. If you see this mouse on sale, at least based on these first impressions, I'd say buy it with the dock. (it's currently $120 on Amazon US with the dock included which is why I purchased it). **Update April 30th** Only 2 days of use now, I realized my battery was draining over 10% an hour with 33% brightness on RGB and 1000 polling rate. I dropped the RGB lighting to 0 on the mouse and polling rate to 500 hz, now it's about 1% per hour of gaming time so it seems to be falling in line with the 100hrs of use at that point (note, this is not in low power mode which I haven't really tested well yet). I preemptively put a ticket in with Razer to see if I had a dud or not initially but it seems like if this actually holds at 1% per hour in current settings, it's plenty, i throw it on the dock over night anyways but at this rate it can last 4-5 days of playing without a charging it which is quite impressive. Update after a couple weeks of use: I'm very happy with this mouse, it is certainly extremely customizable. I previously mentioned I managed to get the battery life alot higher. Now after a full day of gaming, 15hrs + I'm barely even getting to like 81-85% battery which is fantastic. Charging it so mindless with the dock that I don't think anyone will ever worry about it. Overall my only complaint is that the clicking feels a bit wobbly, my logitech mice clicks are generally very firm and there's no movement of the click buttons side to side whatsoever, but otherwise, the mouse itself is fantastic, extremely comfortable and again the closest thing I could get to a g502, the scroll wheel has a nice feel, the rest of the button feels very good with each click feeling fantastic.

I’ve been using this mouse daily and I’m genuinely impressed. It’s incredibly comfortable to hold—even after hours of work, my hand doesn’t feel tired or strained at all. The ergonomic design makes a big difference. The clicks feel satisfying and responsive, and the side function buttons are very practical, making multitasking much smoother and quicker. But what really sets this mouse apart is its precision—whether I’m doing detailed work or just browsing, it tracks movements perfectly. Highly recommended for anyone who spends long hours on the computer and needs both comfort and performance
