Good value
Very simple to setup, and does what it says, however the knobs can be a bit better and more accurate when tuned, otherwise does its job and extend your reach by far more than expected

Did not provide any noticeable amplification of the signal
Did not provide any noticeable amplification of the signal. Even took output from one channel and ran its output as the input to another channel, resulting in a doubling of the amplification, with no change in the quality of the signal.

Amp
The 4X4 RCA video amp performed as expected. It was simple to set up and to adjust. It provided a setting which worked good under the conditions.

Terrible
Terrible product. Does not even work and seller would not replace. When the seller was contacted about return/ exchange, I was told since it was outside of a month (by like 2 days) they would not replace it with a working unit. Had a pro check this out in our setup and he said we needed a better quality piece. For the price (over $100!) we paid it should have been the best quality.
