Summary: I bought this 'booster' because I have 2 towers within sight of my shop but the signals are weak and spotty. I installed the booster with the antennae in the window and pointed at the towers. Although teh lights show that it is working normally this 'booster' has done NOTHING to improve signal strength. I can only conclude that 'normal' for this device is synonymous with 'useless'. Don't waste your money.
Summary: Where we live, we have no signal in the house so we have to go outside to make a phone call. It makes running a business from inside the house impossible. I thought maybe this thing would make it so I could talk on the phone in the house. NOPE. Its in my office, and I still have to tell clients to wait until I can get outside. Not worth the money or annoyance.
Summary: Don't be fooled by the advertised 1500 sq ft. At that range you will have very minor boost in signal. I normally have 0 to 1 bar of reception in one small area of the house. I now have full bars as long as I am within 5 ft of the booster. I use this with a bluetooth repeater connected to a regular cordless phone so I can go anywhere around the house. You must try different locations for both antennea to get the best reception and they must be 8 ft apart.
Summary: I just received my zBoost YX540 Metro. I have five bars outside my apartment but virtually nothing in so my hope was to bring the signal inside. It does bring in five bars but the 1500 feet broadcast zone is pure fiction. The phone needs to be a foot away to get five bars and drops to nothing in two. Save your money.
Summary: Before I installed the Metro I could sometimes get a signal from within five feet of the front door. The problem was we just installed a metal roof, there's chicken-wire holding the insulation in place, three of the four exterior walls are basement walls, and all walls are made of concrete block.
Summary: It works, but not very well. I live in an apartment that sits in a gulley. My cell phone signal is sporadic, thus I get dropped calls a lot. I was hoping this device will help. It doesn't. I still get dropped calls. The reason I said it works because before I got this device, the maximum number of bars I got was 3 out of 6. With this device, I can get 4 out of 6, BUT it can still drop to 0 bar.
