Performs better than it looks.
This is a great funnel kit for a garage mechanic. It has the flexibility to fit multiple size radiator openings. It’s a good design that makes it easy to fill the cooling system. Very durable, sturdy plastic funnel with a cover, which I use for storing the additional sizes of adapters. This funnel makes “burping” and removing air pockets when performing a complete flush and fill.

Works well and compatible with 2019 Honda Insight
Used with 2019 Honda Insight. Using the color matching helped speed up the process. For the 2019 Honda Insight, the radiator cap that is compatible with is the BLUE set. Everything is well-made, the caps are metal, while the other accessories feel like high-quality plastic. This device allowed me to perform my own drain-and-fill on a vehicle with about 62,000 miles using Honda Longlife Coolant type 2. I was able to do it quickly and mess-free; it took more time waiting to drain the coolant than it did to refill and run the vehicle until the engine reached operating temperature (with the heater on). I thought the price was reasonable as well, compared to some chain stores that sell it at $59.99 for similar products.

Works great, eliminates mess and overflow when refilling coolant
I can't believe I put off buying one of these for so long. This radiator coolant filler works exactly as I had hoped and was a great aid and getting the air out of the system when I refilled it. Use it last week on my wife CRv And I'm going to use it today on my side-by-side. If you're thinking about getting one just go ahead and buy it I think it's really necessary and helpful for refilling coolant in vehicles.

Worked great. Made the job easier.
This is one of those things I will use maybe a couple times. But it made the job so much easier and cleaner that it is worth it to me. This particular kit is well-made and doesn't feel cheap or flimsy at all.

EPAuto Spill Proof Radiator Coolant Filling Funnel Kit
It made draining, refilling, and bleeding the air from the radiator and coolant system of a 2014 Camry very easy (it was compatible on the blue fitting of the kit). I only used the blue component of the kit, which appears to be designed for my specific Toyota model; I cannot speak to how the other colors fit. It seems to be a complete kit at an affordable price a great kit for DIYers. Looks will last for years, the right size, compatible (at least for my Camry 2014) make it mess "free".

Good funnel kit
This funnel was perfect for removing air pockets in my coolant system. All of the parts are good quality and made a strong seal to prevent spills from happening. There are also a variety of fittings for many different types of systems.

worth the convenience
I haven't used every tip, but the ones I did had a really great fit, at first I thought on just using a plastic water bottle, but after biting the bullet on the 20$ spend it's genuinely one of the best 20$ I ever spent, made the job VERY easy and I couldn't imagine how much harder it would be without it. Doing something like flushing the coolant on a car isn't rocket science in any capacity, but it can be really time consuming, and frustrating waiting on the bubbles to come out/burping the system, but this made the job frustration-free...it was really stable too, I moved the car 5-10mph for example while moving it around on my property and it didn't spill or fall over at all.
