I struggled a bit with the installation and finding a suitable power supply, but it was worth the effort and the money.

Basically, I have been using it for 2 days and so far I have tried it in various ways without installing it on the wall yet. From my initial impressions, I have a very positive opinion and I have not identified any negative aspects.

It seems to be a high-quality construction, it has several settings, it works even without a battery, and its price is quite low. It has a powerful siren and very detailed instructions in Greek. Only time will tell

Very good construction and powerful. It is placed in a house outside a village in Arcadia in a remote area and can be heard all the way to the village!!
