The right capacity and right size
Placed this water heater under the sink of my shop. Easy to install. I ended up buying two water lines of the same length since I needed female ends of one of the lines.The heater has provided me all the hot water I have needed. I turned the water temp down 1/4 of a turn from high since I didn't need the water that hot. Great product, works great.I have to turn the water off to my shop in the winter so I have yet to see if I can blow all of the water out of the tank or if I have to remove the tank to drain it for the winter.

It's a 5 star from hubby!
Ok, the size was different than our instant water heater we are replacing in the camper. But that's expected since this is an actual water tank. It's going to get even more use this coming weekend as we will be in the caper all weekend, so I can update even more.It is easily installed (hubby liked that part), seems quality and durable (we will know more as time goes by). We are pleased so far with this purchase!!!I would recommend this for a camper or under a kitchen sink for faster hot water!

It works
Easy to install... Replaced the tank in an RV with this. It works but you can't take long showers.

Failed early.
Installed easily; worked as expected. After a month it tripped the GFCI socketed that it was connected to - but would work if connected to an unprotected circuit. Two weeks later it stopped heating, while still showing the red indicator light.

It can be used both stationary and portable.
I really like that this heater can be used both stationary and/or portable in case you need it, which is great for tent camping or handmade campers. So basically, you can use it everywhere as long as you’ve got water and electricity. It runs almost silently and the water heats up very quickly. It came with a wall mount and two hoses.

PERFECT LITTLE WATER HEATER
I actually had purchased and installed this unit under the kitchen sink for a friend. It works perfectly, providing instant hot water, instead of her having to wait 2-3 minutes for the hot water to reach the kitchen faucet, which of course was wasting a lot of energy and water. I also liked the thermostat and the on/off indicator light to let you know when it is heating. I am so impressed with how this thing works, that I have decided to buy another one, for my own kitchen sink. :-)

Easy setup
Put this under kitchen sink. I usually hesitate to give reviews until I have had an item long enough to see if there any problems, but this water heater was easy to install and worked perfectly right out of the box. I would have given it 5 stars but haven't had it long enough to know how durable it will be, time will tell.
