Maximum satisfaction

Considering the importance of the purchase, I had the opportunity to discuss it, speaking directly and obtaining answers and assurances. Not having to deal only with an automatic responder, I found it essential to then have maximum satisfaction with the product purchased.

PIERO PAOLO F.

HDMI extenders

I am very satisfied with the purchase, fast shipping, I received the package in a few days!

Claudia V.

Bulb ok

The supplier is competent. He understood my problem and suggested several solutions. It deserves 5 stars even if one of the 10 purchased bulbs unfortunately burned out after two days

VB

Electrical outlets

Despite the delivery times, which were not very quick, I found the purchased item really useful. I was looking for a product for a Bticino matix plate that would allow you to connect a fiber optic socket, an item that Bticino does not have in its catalogue. The object I purchased responds perfectly to the need and as reported in the description is compatible with the Matix plate.
