As with anything, hype is hype. That doesn't mean they don't work. Take the crazy claims you hear about increased distance, and cut that by half. Then cut it by half again. The increased distance you get from Microwaves isn't worth the cost of installing them, by itself.What is everyone's opinion on the MicroWave guides? I have thought about using them but always go to Fuji's. Do they really help with distance?
