Off the top, this product is well designed, and assembled with quality components. The instruction manual could be better, and it would be excellent if someone could find a link to it online. If I am able, I will take photos of the manual and post it with this review.The water tastes great! I purchased this unit to get myself into the habit of drinking more water, and will probably add around 1/8 teaspoon of Celtic Sea Salt to remineralize the water. I find myself craving this water now, and with the built in cooling function, it makes everything quick and easy.Features: Hot, Cold, and Room Temp water on demand. Perhaps the best feature is that you can press a rocker switch on the back of the unit to start a 90 minute cycle to pump pathogen killing ozone directly into the system to clean the tanks and the lines. It's also worth noting that the instruction manual includes instructions for removing the water tanks to clean them independently, which I would definitely advise you to do at regular intervals. The instructions don't say how often you should completely clean the unit, but I'm going to check it out at 3 months, and then I can't imagine it being necessary more than once or twice a year (if that).I believe the ozone feature is important, as many RO systems show an accumulation of bacteria in the reservoir over time. I have performed the ozone cleaning cycle once already, and if there was any ozone gas leaking, it was minimal as the ozone odor was extremely faint. Plus any leakage would just clean and refresh the air around your cooler!I started off trying to install the system by splitting off of the 1/4" line behind my refrigerator. After 3 days and 4 trips to the hardware store, I reread some of the reviews and realized I would probably get better results splitting off of the cold water line coming in for my washing machine. This worked out great, because it provided additional pressure, and I wanted to place the cooler in the laundry room, so I didn't need to drill any holes.To split off from the cold water line, I used a standard 3/4" garden hose "Wye" connector, to which I reconnected the cold water line to the washing machine, as well as a 3/8" OD x 3/4" FH "Dishwasher Elbow". Lastly, I purchased a 3/8" OD "Cap" to cap off the end of the splitter that ships with the unit. On all connections, I made sure to use the included PTFE sealing tape. This is critical. In the future, I will probably purchase a gasket from a hardware store to further prevent any leakage from the cap. Caps are notorious for leaking, and I pretty much got it stopped by adding a second layer of teflon tape to the connection point for the cap, but a rubber gasket would definitely improve things, as I can feel a tiny amount of water leakage at the connection when I check it after a couple of days.For the drain line, I just ran it out of the back of the unit and pushed it down the drain line in the wall where the washer water drains.The install isn't the hard part, it's finding the parts. Hopefully this review will help you out!Note: After installing I reached out to the company to check on the availability of parts. I was told that they do keep parts on hand, so serviceability should be taken care of.When you look inside the unit, they are parts that should be easy to locate, and there is enough room to get to things and make your own repairs if the pump or compressor go out in the future. All in all an excellent product at a really amazing price. A+
