Purchase Feb. 24 lasted until Oct. 24, 9 months that is, (it no longer has a signal output while everything looks good)... I sent a message to scroutz for repair or replacement today, waiting... (to be fair, the larger equivalent "edision hdmi lite dvb-t mpeg4 1080p full hd" I have had for over 2 years and it still works with minor issues), like if it loses power it loses the settings you have saved, e.g., channel, name, etc.) but it still works.
update: They sent it back to me from service in a week, and it works perfectly.

Quality and really does what it promises. Without many words, I send a digital signal from Digea Nova Cosmote NVR camera recorder and Home Cinema to all the TVs in the house with HD image and crystal clear sound without any image or sound interruptions or any other problems. Experiment a bit with the signal strength settings and, most importantly, check where Digea broadcasts in your area and on which channels/frequencies it broadcasts so that you don't put the modulator on the same channels/frequencies and have interference or interruptions on your screen. Very important, the HDMI cable you connect should be of excellent quality (preferably with gold-plated connectors) to avoid any problems. It's worth every penny and more.

Excellent product.
Without any special experience, I managed to set it up myself by reading the manual.
I also have the Lite version, which does exactly the same job but is almost twice the size, so I preferred the mini version the second time.
Attention, if you have more than 1, select default programs so that the signal does not get confused.
