  • So far so good
Style: 2.5 Gallon
The media could not be loaded. Nice size, Heats up really fast and super easy to install. It’s enough for doing the dishes. Also easy to operate, just turn the knob to adjust the temperature. Works as it should. Very good 👍

  • Really good hot water alternative with short bursts
Style: 2.5 Gallon
Took a while after getting this to review. Wanted to have it installed and see how it holds up. So far it works as expected. There will be a necessity for a decent amount of space if it goes underneath a counter. This is basically for an area that needs hot water but really only has one cold waterline. A waterline conversion may be necessary but we were able to easily source the correct fittings to install it without any leaking. 2.5gal of hot water won't last very long so we use it in bursts. Since we aren't using it underneath a counter, we don't have fit issues. Cannot comment on the lifespan because I'm sure it will become calcified with the city water as ALL items do that we use city water with. Will try to find a way to maintain and decalcify it. Overall good value. ... show more

  • Heats water fast!
Style: 2.5 Gallon
So nice, with a shiny white shell. It gets water scowled and hot in a very short period of time. If I use all of its hot water, I just have to wait five minutes or so and I have more.
