absolutely great addition to the RO system. flow greatly improved

Must have for fridge connection

We were having issues with our tankless RO system cycling one and off when we pulled water from the fridge. This completely solved our issue.

Instructions are very poor. The sealing washer supplied is much too large. No phone number given for customer service.

Works great. Result is filling up a glass (or pot, etc.) with water faster. Well worth the money to increase the performance of my tankless RO system.

I was not getting a steady flow of water, after installation it is perfect!

In the process of installing the unit, I noticed it was leaking and put some force to stop it, nothing extraordinary and as you can see if the picture the part where the on/off is broke. When working with water parts must be thought enough to tighten to avoid water leak; this one did not pass the test.Not recommended at all.

This definitely works when you have a tankless RO, but the amount it provides before my RO kicks in is just not enough. I love having tankless for when I want a few gallons, turn it on and walk away. I also love having a tank for quickly filling a bottle or glass. This says it's 0.13 gallons, so just over a pint, but I lose pressure about 10oz in and the RO kicks in and takes over. I think I'm going to need to upgrade to something about 3x as big.
