The build quality is very good, with excellent shielding and very good performance even in the rather problematic area of my house, with a hill and tall buildings in front, all of which block the repeaters from view. The only negative, but I think it is not essential, is the lack of a metal clamp for mounting on the pole, and this is because the plastic tie dries out over time from the sun, resulting in the amplifier eventually hanging from the cables and needing to be wrapped with tape, as has already happened to me in another installation with an amplifier of the same mounting type. Because the metal one may rust over time and not unscrew, but it doesn't break on its own, except when we destroy it ourselves to replace the amplifier for any reason. But since overall the amplifier is very good in its performance, with a low setting it drives four TV receivers with the help of the OMS-2 splitter from the same company, that's why I highly recommend it!
