Mizudo item FDG-CS90 FAILED after 5 months! I cannot find any support for repair or replacement. Totally unacceptable.WOW Jessica from the MIZUDO customer service reached out to me and they sent me a new unit with no questions asked! No detailed description or any other details were requested. I NEVER had such a wonderful experience with customer service! Thanks, Jessica, you're an Angel.

I installed a 5.1 gpm in my RV. Couldn’t be happier. This was #2. As the first one had an issue. Amazon took it back and sent a replacement the next day. Works perfectly. Customer service at Mizudo was extremely helpful and friendly.Good choice to make!

Not working and no repair parts available. Waste of money. Transistor on mother board burned out and can not find replacement part. Had two service people look extensively from manufacturers company. So sorry we actually purchased twoof these units, one for my daughter's home and one for our own home. Hers lasted almost 5 months. I'm afraid now to install mine.

We installed this water heater for our tiny house 5 months ago and it has been wonderful. The water gets hot really quickly, and can get REALLY hot. I actually had to turn down the max heat temp. because it would get too hot! It also stays hot, though sometimes struggles to maintain the exact same temperature, but it never goes cold (and for this price it is working astonishingly well). Our shower is outside so hot water is crucial in December. Seems efficient, too, we haven’t yet had to refill our 100 gallon propane tank in the entire 5 months we’ve been using it.

I have a small 1200ft house with just my fiancé and I. This works great for our needs! Do research on the install as it’s not your normal water heater connections. I placed a larger 4” metal dryer vent hood through the exterior wall then routed the smaller vent pipe for the unit through it (vent pipe is smaller, 3”, so it doesn’t touch the homes walls). Water pressure is great, heat is very good, the only caveat is if your turning on and off your water (say washing your face) it’ll have to shoot out the cold water from restarting before it gets back to hot. Overall great purchase as it also should save money from not having a lite water heater 24/7. If you have hard water (I don’t) then maybe install a filter in line or flush your unit once a year with vinegar.

Plenty of hot water for a small household and so inexpensive.

Recently had a power outage for four days due to a storm, and if one happens to have an all-electric tankless water heater, one had better also have some sort of a generator in one expects to have any hot water. Sometimes gas is the better option, and if such is the case for you, this unit, or one similar may be worth a look.For what it is, what it does, and what it costs: Four StarsI am the Totally Unbiased Reviewer Dude (T.U.R.D.) and that is how I see it.
