Worked good the first day water was hot. After that just a little warmer than tap water. Waste my money. Easy to install. It would maybe good for a camp or something but not for home purpose

I'm confused on how to use this. The description mentions use for "Outdoor showers, Pool Side showers" and other outdoor examples, but the sticker on the unit specifically says INDOOR USE ONLY. The instructions say that you must locate the shower head a MINIMUM of 6 feet from the plug, but the cord is only 5 feet 10 inches. Plus, if the head is installed at the minimum height of 6 feet, that means the plug has to be 6 feet high too, since any angle would make it less than 6 feet away. There is no way to replace the cord, no way to hardwire it (as the instructions recommend, which is even more confusing), and you can't use an extension cord.
More confusion arises on electrical requirements. It says to use 10 AWG minimum, but the cord is 12 AWG (which only supports 20A). It requires a 30A breaker, and it says it draws 23 amps - but the largest standard receptacle made only supports 20A (L5-20), and you'll only find a 20A breaker on an L5-20 circuit. Any 20A outlet you find will also only have 12 AWG wiring.
Beyond all that, I tested it by connecting it outdoors to a 20A circuit. I set the flow rate to 0.75 GPM, and purged the air as per instructions. I started by taking power readings. There are 5 temperature settings; readings were, from Low to High: 9.5A, 13.5A, 16A, 18.5A and 20.3A. So at all settings except High, it was actually within the 20A breaker limit. Unfortunately, it always starts on High when you plug it in.
I checked the water temperature with my hand when it was on High, and it was really hot - too hot for a shower, at least 110 F. Then I grabbed the thermometer to take readings, but something happened - I'm not sure what, but it basically broke. On High, it dropped to 90 degrees. My inlet temp was 75. It was still heating a little, but not like before. I adjusted flow to make sure the activation point was reached, but no success.
Testing aside, I don't think this puts out enough heat to be effective even if it works as advertised. You would really want to use it when the water is very cold, which means you would need maximum heat, which means running it at 0.5 GPM. You're not going to get much shower at that rate.

Rated 4.0 out of 5.0 by moonrise Great if you have 30 amp breaker available
the unit looks nice , unfortunetly the cord is only 6 feet long and the outlet is 8 feet away, so I was unable to get a good shower, I think it would work great , but the wiring is another bumble, as it requires a 30 amp GFI, and the wiring only has 20 amp breaker, so that was another set back,, please make one with a longer cord, and 20 amp able!

Rated 1.0 out of 5.0 by toots worthless warranty
Electrician required for installation for safety, which was OK. We have low water pressure so that feature of this device was desirable. There is no hand held shower attachment which is undesireable. I bought 2 units for use in 2 bathroom showers. One works fine. One ceased working after 3 days and 6 showers. I have been very poorly treated by the manufacturer in my attempts to enforce the warranty.

Rated 5.0 out of 5.0 by torkelk great little unit
I used this to boost the warm water in my shower. I do not recommend if your trying to use this with freezing water temps. It does a great job for me.

If you are on city water, decide which is more important, water pressure or temperature. The warmest temperature we got was the temperature I would give my toddler a bath in, and the water pressure was so low we had to double our shower time in order to rinse off properly. There is no way to adjust the water pressure on the unit itself. You have to adjust pressure using your tap.
