Review: It works very well - It works very well, it replaced a failing amplifier nearly 35 years old. What a difference , great bit of kit although I can’t comment on longevity. Great picture and strong signal on all channels.

Our original splitter box was over 20 years old (before mobile phones). The SLX six way splitter/booster was very easy to swap and the improvement in signal was miraculous. All our HD channels returned with much improved the signal quality and the number of channels increased dramatically. A perfect solution.

The SLX 2 way booster works ok. But when opening the package the box it was in was damaged. Looks like it was opened then put back in its box.
