RV Motorhome Retrofit Door 6 Gallon Water Heater Device Unit Polar White

I have purchased this tankless water heater knowing it had a few low star ratings. for the installer like myself if you follow the parameters that are set in place for installation.and follow the guidelines of how the water heater works. Then it is an out standing water heater.our first experience with it is we both used our shower in our camper 15 minutes at a time back to back. Had all the hot water we could use and never run out. there was not any heat fluctuations it stayed the same temperature the whole time. and if you did have any questions call the tech support which is highly helpful. The person whom I talk to was very nice very helpful and knew the product very well.I am NOT one that ever does any ratings on any product. But I really like this unit and looking forward to our next camping trip.

Hole was in the wring place by 2.5" to the right of where is should have been. Drilled another hole now I have to patch the original hole. Pain in the butt!
