Waterdrop Reverse Osmosis System, Instant Hot Water Dispenser, 600 GPD, Reduce PFAS, Tankless, 2:1 Pure to Drain, Under Sink, TDS Reduction, Smart LED Faucet, Hot and Cold Water Dispenser Faucet

I just finished installing this beast of a unit. Make no mistake, this is a beast of a unit. I don't think I ever grasped how big the base unit was or how tall the dispenser was. The base unit takes up the entire left side underneath my sink.. probably 25% of the space under there. Maybe more since the pipes and lines intrude on so much.I was installing this in place of an old insinkerator filtration system. The hole was a tad bigger than I think this waterdrop unit wanted so screwing in the nut to hold the dispenser in place wasn't quite as easy as I had a hard time getting it as tight as I thought it needed to be. The hole was a little big and there was not a larger spacer/washer to allow for that. Really the only thing I thought they should have had in the system that wasn't there.After suffering through uninstalling the old unit, installing this waterdrop ro system was really quite easy. I thought the hardest part was drilling the drain hole and then shoving the tube in there. That was hard as the 1/4" hole was too small for the tube and I had to enlarge the hole a little at a time until I could shove the drain tube in. After that, it was really easy. Everything is clearly marked and the tubes go into quick connectors very easily. I did have to read through the setup guide after the install to find out that the system wants to flush for 15 minutes after install to get everything through and before any heating can occur. That's fine. I just didn't know this until I read it. The 60 second flush is normal for any filter so that was expected.So far the unit is pretty awesome. After overcoming the shock of how big it was and getting it finally installed, I think my family will very much enjoy using this. There is no taste to the water and the instant hot water feature is so nice. We had that with the insinkerator until a 3rd tank broke. I wasn't about to get another tank. Hated having to deal with those.It's very early but it seems like this will be everything I expected and maybe even better than I expected. I had mentioned the dispenser Sat pretty high... It sits around 10 inches high off the counter. That's fine. I just wasn't expecting it. Hard to gauge in pictures. But the touch controls and the overall function is really easy and nice. The water coming out seems really fresh. I had some cold and it truly came out cold and it was very refreshing.

This unit was very easy to set up, the TOD is incredibly low, and the hot water is always there on demand. I am so happy I don't have to buy distilled water for my water kettle and wait till it is hot. One push of a button and I have my tea with the purest water. My husband uses the room temp filtered water for his coffee machine and the machine is as clean as it was with the distilled water-no mineral deposits.I did have one issue with hooking it up, but thanks to Rebecca, I received a needed part and a free water pitcher "for my patience", but it didn't require patience because they sent the part out the same day. This is a fabulous filter with outstanding customer service.

The product is amazing. Ease of installation and the water taste as describe. The price of the product is ustified for its quanlity. Strongly recommended.

Installed the system by myself took about 1.5hours including removing the old faucet and filter, while we had a hole on the sink so no drilling is needed. I was a little worried about the water flow as there are higher water flow (800-1200 gpd) version without heating function but i found 600gpd on this product is actually quite good, which is similar to those bottle filling stations at public locations. The instant heated water is the best part of this filter. The hot water can reach its temperature target in 1 second when turn on the faucet and the real time temperature display is very helpful.Very pleased with the product and believed it to be the one of the must-haves in our kitchen.P.S. if search this product at Rednote App, there are distributors having discounted price since sometimes amazon price can be high(>$600).

Never tested quality of water, just trusted TDS display. Tasted and smelled ok. Instant hot is the problem. Was always on at random times with loud churning noises. At one year the lock button no longer functioned. Then another 10 months (now) it made super noisy nonstop 80 db freight train sound until I unplugged it to make it stop because all other buttons didn’t function. I cycled it on again but kept getting E05 error and no hot water. Worse of all as E05 error tells you to contact Waterdrop right away ( 24/7 service my A…) there is no answer. Called next day got some dumbo who made me do the whole cycle all over again though I said I already had multiple times. Guy kept talking over me like a robot to get thtough his script and ignored me. Said if it didn’t work after 15 minutes to call back to ‘escalate’ it. Of course after 15 minutes it didn’t work. Left hanging on phone cue after 2 hrs (‘you are 1st in line’). No answer. Friend tried calling while I was 1st for over 1 hr got fast busy signal repeatedly. So much for customer service.To sum it up DO NOT BUY!! Get whole house RO and standard instant hot tap instead. This product is nothing more than a cheap ‘Made in China’ piece of trash. So is the ‘ customer service’.
