I think that Ferro makes some great products. Bravo to the Polish! I like that the company follows the philosophy of being able to repair the products it provides to consumers and emphasizes DIY. If you visit their YouTube channel, you will see that they also have tutorials for various batteries, etc.

Apart from that, the booklet that comes with the battery also includes maintenance instructions. Rarely or never do you come across battery manufacturers that tell you to disassemble it to clean mechanisms and components (or replace them when needed).

Their products fall into the value for money category and in my opinion (based on what I have encountered and compared), they are very fair. They cut costs in certain areas (such as the quantity of metal) but only as much as necessary, and it shows that they pay attention to details, such as the finish (casting, machining), which is impeccable. Another example that can be seen in the photos I have attached is that I removed the filter and found that the gasket is made of silicone and not the common black rubber that you find in most batteries on the market, which after a while you remove and it leaves that black residue on your hand. It undergoes quality control and a seal with the production date is included in the documentation.

I was looking for a battery that does not have the common (and annoying) mechanism with the pull button to switch to the shower and does not exceed a certain price. I chose this one and I have not regretted it at all. It's very easy and simple, you rotate the ring clockwise (half a turn is all it takes) from below and it stays in the shower for as long as you want, regardless of the water flow. You turn it counterclockwise and it flows again from the faucet.

Points to note for potential buyers. The rosettes are "thick" with a thickness of 20mm and a diameter of about 60mm, so make your arrangements if you are going to use them (in my case, I installed them because they come with the tile and the battery's nut, so there are no gaps in the threading). Some people may not like the fact that the shower outlet protrudes so much from below (due to the switching mechanism).

The company states in the documentation that the 5-year warranty is provided for both the mechanism and the body of the battery, but whether one will be successful with Greek merchants is another story, although I don't think anyone will need it (I have had it for 2 months and it has not presented any issues). It is also not clear whether it is manufactured in Poland or elsewhere. The packaging only states (in English) the manufacturer: Ferro, blah blah, Poland.

After I purchased it, took photos, and installed it, I later discovered that someone had also done a "unboxing" in the video below: [YouTube link]

EDIT: I wrote my review for the battery when its price was at €50 (the same price I bought it for), I don't know what is happening in the Greek market now, but it is not sold anywhere else in Europe at this price. The price ranges from €40 to €50+ everywhere else.
