I had to change my review from 2 to 1 star. After about 2 months the unit started to spit out water
at random times WITHOUT any intervention from me. Finally it got too much and sent email to
Anaheim manufacturing who called back within 3 hours.

The rep went through a litany of weak reasons why it is my fault (installed incorrectly, pinched hose,
hose too long, water pressure too high). basically told me:

Buck up buttercup this is the way it was engineered and YOU LIVE WITH IT. (no help from them)

There were 2 things wrong with the unit (so far)

Had the exact same model for 5 years and finally stopped heating water. I am sure it was
from lime buildup so I bought an exact replacement (so I thought)

1. They provided NO 9/16 socket to tighten the faucet to the counter. What is needed is a
deep socket wrench that also had a large interior diameter opening (for the post itself). Other
faucet vendors provide specialty tools, so should they.
2. They did not provide any connection pieces to attach the cold water line to the shut-off valve
other than a compression fitting, which does not work on the water lines from the faucet. Fittings
should be included to match the faucet to a non-compression shut-off.

I've installed this several weeks ago and it seems to be working well and without any major issues. The faucet itself appears to be of high quality and looks very nice. Time will tell if the tank system will hold up over years of use. The only issue I noticed is if you turn up the temperature setting too high on the tank. If you do, then you may get some hot water spurting out the faucet from time to time. I resolved this by dialing own the temp setting until this phenomenon stopped. The water is still plenty hot for hot drinks.

Also, I added a filter system to the hot water which works fine but takes up more room under the sink.

FIRST IMPRESSIONS AT TIME OF PURCHASE:
Not great. Drips for several minutes after every use. Drips continuously while heating even if the temperature setting is low, apparantly the condensate return line is insufficient, and I have triple checked that it is clear and unobstructed. Also the faucet valve started leaking out the top of the fixture recently, only about a month of use. The plastic hose delivering the hot
water to the outlet gives a very strong plastic flavor. I'd return it if I could.

UPDATE, 07/29/2017
This product is working better and better. Initially I was unhappy with it but almost a year now, it's great. Maybe there was a break-in period? Don't know, but the constant dripping has stopped, the off flavor is gone, and it works trouble free. My revised opinion is very favorable. I'd recommend to others to go ahead and get it, and be a little patient while it breaks in. The more you use it the happier you'll be. I would buy this again.

Purchased this product to replace a previous unit that started leaking. Read the reviews and seemed like it would be a product that would last for at least a few years. A week after the warranty was up it started sputtering, barely dripping and then just stopped working. Pulled out the manual unhooked and cleaned lines, hooked back up sputtered worked for about 1 week at a small drip and then stopped again. Unhooked everything again, almost burnt ourselves when it started randomly sputtering. After that it worked, very slow stream, for about 2 weeks if you pulled the handle the opposite. It seems crazy to replace the handle at almost $200 when the first one barely made it a year. For a product this expensive it should work for more than a year. VERY DISAPPOINTED!

Just bought and installed this, so reserve the right to update if problems come up..but wanted to share some installation tips. As others have noted, the faucet doesn't seem to match up with anything for connections. Also, the instructions say to use a saddle valve or put a t into your supply line. I don't have access to my supply line, so had to go a different route. My shutoff valve coming into the cabinet from the wall has a single outlet to connect to the cold water of the primary faucet. I thought I would have to replace the valve with one that has two outlets, which would require turning the water off at the street. Was happy to find a different brass fitting at Home Depot which allowed me to simply shut the valve off, disconnect the cold water supply line to the main faucet..install the brass fitting with two outlets and then reinstall the supply line to the faucet. So now I have a spare outlet available to run to the new hot water faucet provided in this set. The problem (or problems, rather) are that the outlet from the brass fitting is a male as is the supply line leading to the valve from the provided faucet...the second problem is the supply line connected to the faucet is relatively short. I saw a review where someone was able to solve this with a 4 foot dishwasher supply line. Rather than having that much coiled up behind the sink, I purchased two 12 in supply lines and a coupler. This left a female connection at each end to connect to the faucet supply line and the outlet of the new valve fitting without too much extra coiled up behind the sink.
So my hardware store list:
2 12 inch supply line hoses
1 brass couple to attach the two hoses
1 brass splitter to put on my shutoff valve for the cold water supply
1 outlet splitter, since I only had two electrical outlets under the sink..the one in a switch for the disposal and the other for the dishwasher

Total was about $30.

I've noticed the sputtering others have seen if I have the heater too high, but turning it down seems to help. Otherwise, the faucet is great quality, very heavy and matches our current brushed nickel fixtures. The tank warms very quickly and within a few minutes of plugging it in was getting 190 degree water. Installation was actually pretty easy after I laid it out on the table and did a dry run of how everything would need to come together. It fits fine under the sink with a disposal in the center and recycle and trash bins under there too.

So far, very happy with the purchase and wasn't put out by having to spend a few bucks for the installation parts.
