## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Value works very well less than a drop escapes when disconnected/connected
*by J***T on June 11, 2021*

These are very high quality. They work very well and when disconnected the amount of liquid that escapes is minute less than a drop. Installed on an EK-Quantum Magnitude D - 2066 Nickel + Acetal water block. The price is a great value, they are very well machined and assembled. I would buy again for sure. The only issue is size availability. I was unable to find 7/16" x 5/8" so I bought 1/2" x 5/8" which worked fine for my 7/16" x 5/8" Primo-chill tubing. I would have preferred the correct size and looked everywhere but could not find a listing for them.

### ⭐⭐⭐⭐⭐ No Leaks
*by K***. on January 30, 2021*

No leaks and its a cool setup. Just wish it had a manual cap for backup just in case.

### ⭐⭐⭐⭐⭐ Perfect after 3 years in operation
*by A***R on January 17, 2022*

Looks beautiful and works great
