Cell Phone Signal Booster Antenna for Verizon, AT&T, T-Mobile - Truck & Car Mount Passive Repeater
This Cell Phone Signal Booster Antenna for Verizon, AT&T, T-Mobile - Truck & Car Mount Passive Repeater does not boost signal at all. I can not tell any difference on my signal on my cell reception. I personally would not recommend. But I cannot return because it is stuck hard on my car. That is one thing is that is good.

It didn't make things worse.
I still don't know if this works or not but it didn't make things worse. For the price it was worth the gamble but it may be mostly placebo effect. easy to install and no power necessary.

no improvement at all
inside RV no cell phone signal, outside good, so bought this antenna to boost the signal inside, installed it as described, cell phone about 3ft away - still no signal inside, therefore this antenna is not working as described, have no improvement inside, just waisted money for nothing.

It works.
I don't know what problems these other people are experiencing, but this thing works great! It was easy to install and I immediately noticed a difference. FYI, the package specifically states that it's not for home use, but works great in the car. Also, if there's no signal, there's nothing to amplify, so nothing will happen and you'll be disappointed. I used to hardly get any signal in certain areas and would miss important things and not be able to complete my job until I drove somewhere that I could get a signal. That's all over and now everywhere I go, I can do whatever I need to and I always seem to have service now. Bottom line, this thing was cheap and easy and solved my issue of constantly going to mountainous, wooded areas and expecting my phone to work. If there's any signal to be had, you'll get it. Just don't try to put it in the house. It's for your car.

Don't buy - doesn't work. Product does not work but actually makes the signal much worse in vehicles. We tried testing this for a week, and found out finally why our signal was so bad. I can't find the packaging so I guess I'm out the money. Update: received message saying that the item does not have to be returned in packaging. That response was good.
