At first I was very satisfied with the build quality etc. It was sometimes -4 and it started losing a lot from the temperature regulator. It's a pity, it seemed like a good product.

I installed it at the end of June 2025. The first few months (summer) everything was fine. In the winter, it had a large deviation, it didn't mix properly.
In the end, it didn't last six months. At the first cold, it broke. Wrapped with as much insulation as possible.
Money wasted on it and all the surrounding accessories. At least I had it with bypass valves.

I installed it exactly a year ago in a house for rent. I set it to 45-50 degrees, but I had complaints from the tenants that it did not provide enough hot water. I set it to 60 degrees (maximum) and everything was fine.

I have installed it on the solar heater for a few months now and it works perfectly. No more scalding hot water in the shower and the water pipes are not strained by high temperatures, expansions and contractions.

4 months already installed in the house. Set at 45 degrees, everything works as it should. But come on guys, seriously. In 3 years from 70 to 100 euros... The Italian competitor remained steady at 45-50. We want to support a quality Greek product but we're talking about double the price...

It is very good and works as it should. The only thing I didn't like is that it's difficult to tighten the silver connector properly, resulting in leaks at that point. That's the only part that troubled me. Other than that, the installation was easy on the solar system. The good thing is that the water pressure doesn't decrease.

I put it in the washing machine so I can take advantage of the hot water that I have in abundance, and it has been working perfectly for a year now

Installed in solar for 1 month and it's super. Great convenience if you have a small child and worry about burning them in the bathroom. You turn the hot all the way up and do your job. Easy and quick.

Very good quality, comes complete with check valves. I measured the temperature of the water coming out of the faucet with a digital thermometer and it was accurate

Perfect, very good quality, excellent operation and accuracy in temperature. You place it and forget to deal with the mixing in the shower's faucet. You simply plug it into the hot and take a carefree shower. During the winter, wrap it with insulation to avoid losses.

It is perhaps the only one that is fully equipped with accessories.
I installed it in the basement, where the pipes from the solar panels pass through to the kitchen and bathroom.
With the first one I installed, I had problems, but they replaced it under warranty, after first giving me countless excuses.
With the second one, so far for 6 months, I have no complaints.
So five stars, and if needed I will update.

It still works flawlessly.

It is an excellent product for the solar.
It protects you from burns and the faucet's spiral from wear and tear due to hot water.
It's worth it.

Very good, it does what it says, for me the best, it protects everything: people, faucets, spiral pipes, and saves on hot water

It does its job just fine. Obviously, it's not super accurate, but you don't get it for that purpose. The purpose is to not get burned when the water comes from the solar or water heater, and for that, it's excellent

Very good product.
It does what it says.

ENGLISH
QUALITY PRODUCT
With its fittings, with its filters, easy to adjust.
Installed in a tank in tank inert container in the water for use.

It does exactly what the description says. Stable temperature of hot water and economy of solar hot water as it sends hot water at the set temperature, so you don't lose hot water in the pipes.

It does its job very well, it has a slight temperature deviation and requires adjustment according to the season. What doesn't work at all for me is this temperature-sensitive strip that shows the output temperature.

Amazing mixing valve, congratulations to Brass Form, thank you
