Query: Doesn't work

I ordered this switcher due to the fact it came with a remote and I don't have a HDTV and need a $100+ switcher. Starting to think I should have bought a more expensive model. The remote worked fine, but the box would cut the signal in and out intermittently. The signal would also sometimes vibrate. It didn't matter what device was sending the signal. Maybe I got a defective one, but I don't want to hassle with sending multiple switchers back and forth to see if I can get one that works all the time.Hopefully I will get a refund from Beach
