GFuel Black Out Shaker Cup

It holds liquid in it. And you can shake it with some powder in it to mix the powder with the liquid you put in the cup. You need to shake it to mix the powder. Also it won't leak if you tighten it down enough. I was like wtf? This shiz leaking like a freak. But after I was like let me put more gamer hand grip on this. And it stopped leaking. Bussin shaker 👍

Works like a shaker. No leaks so far. I will update this review If I do encounter issues in the long run. Price wise, it is pricier than one posted on gfuel's website BUT they dont sell this version anrymore. I also dont mind the price increase since i'm not from SEA and buying it via Amazon makes sure it arrives to me :) I've also seen a few reviews saying this is fake, but i beg to differ. Looks solid, doesnt look fake, prints on the cup are good and they are not faded. If i were to nit pick it would be the packaging. The package contained two of the items I ordered: the shaker was bubble wrapped (2 layers) BUT the box it was put in was big. (hence it moved around a lot inside, good thing there's no damage to the goods.

My son bought this after much research on many different shakers. It has been a great, durable shaker. NO LEAKING! It does it’s job. Plain and simple. Easy to clean

Man this thing leaks when you shake it but I think it's because of that piece inside meant to help mix things up is getting in the way. Going to try to use it later without it.

I love the GFuel cups they are so amazing!

The mixer being a grill instead of a ball makes this cup super easy to use and clean and well as not making a huge racket when ever you're mixing something up

It leaks a little bit occasionally. Even if I never touch the cap. It leaks from the top not the bottom so don’t get that confused. Nice size, good with mixing stuff and if you drop it, it’ll probably break a little bit, but it will still be fine. So it is not super durable as in cracks. Functions decent but can leak as if you didn’t close it all the way even if you did. This is not bad, but I wouldn’t recommend this to a friend.

My son’s favorite cup to drink soda with ice

Es un producto un poco caro para lo que ofrece ya que tiene una buena calidad de material, solo que en la estetica de durabilidad no es la mejor ya que a los 3 meses aproximadamente de su uso la tapa no cerraba bien, a si que al beber agua en el embace empieza a derramarse y si lo quieres para el suplemento energetico (gfuel) te recomiendo que compres otro, tal vez a mi me toco uno en mal estado ya que me gusta mucho la marca pero me decepciono en este producto y puede ser de que el producto pudo golpearse en algun momento pero ya no tendria la buena calidad material como mencione al principio. Si decides comprar este producto espero que te toque uno que no tenga fugas.
