Installed 2 months ago for a new heat pump in an old network.. it needed cleaning twice so far but only in its transparent cup and its filter. Its magnet inside did not catch anything. Good but maybe not perfect.

The material is good but the magnet is small and does not hold particles when the circulator is running, it will only collect in stagnant water.
Also, it does not provide crazy connection unions and valves, they must be purchased separately.
Advice: do not use under one inch because the circuit flow is greatly reduced.
Update.
Big disappointment from Brass Form for the second time.
The first time was with a thermostatic valve for a radiator.
The second is with this filter.
It doesn't work, I have installed it on an oil boiler and it collects almost nothing.
The circuit is not clean so that it wouldn't catch dirt, the water is black.
I removed the magnet out of curiosity, unscrewed and took out the small magnets and found that the large cylinder shown in the photo I attached is not a magnet, it's just a chrome-plated metal, the magnets are the three small cylinders.
It's a shame because it's a Greek company.
I will never buy any of their products again.

Excellent filter and Greek does what it promises!!! Installed on a wood boiler with an old circuit, it does a very good job!!!

Quality material. Sturdy construction that looks impressive. The transparent part on the filter helps you see if it has collected dirt. But its durability will be judged over time.

After 4 years, I can say it really is worth its money. It holds the dirt, and as soon as you clean it, it collects more within a week.

This means it does its job. But it needs frequent cleaning. Of course, it depends on how dirty the installation is

Top quality copper and Greek, the magnet is probably the strongest of the others. The fan allows for the addition of chemical cleaners
