Fits my K-Classic perfectly. Glad I didn't have to buy a whole new machine just because the tank cracked!

This HAKANO tank is actually better than the original one that came with my Keurig. The plastic feels thicker and it snapped right into place with zero issues. Saved me like 80 bucks compared to getting a new brewer.

My old reservoir started leaking at the bottom valve and it was making a huge mess on my counter every morning. I was skeptical about a non-brand name replacement, but the HAKANO version is legit. It holds the same amount of water and the lid fits snugly so no dust gets in. Installation was literally just taking the old one off and putting this one on. Highly recommend if yours is leaking or looking gross from hard water buildup. Great value for sure!

It gets the job done but the plastic has a weird smell right out of the box. I had to wash it like three times with soap and water before I felt comfortable putting it on my machine. It fits okay, though it's a bit tighter than the OEM part.

The price is definitely the best part about this product. However, I noticed that the water level markings aren't quite as clear as the original tank. It functions as it should, but the build quality is clearly a bit lower. Decent for a budget fix.

Do not buy this. The valve at the bottom didnt line up with my machine even though it says it fits the K-Classic. I tried forcing it and almost broke the actual Keurig. Total waste of time and now I have to deal with the return process. Extremely disappointed.

It works fine and fits the base, but the lid feels a little bit flimsier than the one that came with my Keurig. It does the job though so I'm keeping it.

If your Keurig reservoir is leaking or looks gross, just get this. I compared it to a few others on here and the HAKANO had the best price-to-quality ratio. Installation took like five seconds and it looks identical to the OEM part.

it’s okay. kinda hard to get the air bubbles out at first but it eventually started pumping water. just a heads up for anyone buying.

Not impressed. The seal at the bottom didn't fit quite right and I ended up with water all over my counter. Maybe I got a dud but I'm returning it and buying the brand name one instead.

Functional replacement. The transparency is good, but I noticed a slight plastic smell when I first opened the box. Make sure you wash it thoroughly before using.
