Cell Phone Signal Booster Antenna for Verizon, AT&T, T-Mobile - Truck & Car Mount Passive Repeater for 5G, 4G LTE iPhones, Galaxies, Pixels

DOES NOT WORK AT ALL. I drive around in a truck on a commercial solar field where the service is poor to begin with. While inside the truck, my phone practically has zero service (SOS mode only), but cracking the window and holding my phone out instantly gets me a real signal.I bought this and mounted it on the windshield just above the steering wheel hoping it would function the same way without having to hold my phone out the window.Real cell boosters cost hundreds of dollars, so for the price I figured it was worth a shot especially given my very specifically tested situation. Unfortunately though it is complete garbage. Don’t waste your money.

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.

como adorno está bien ! Pero que funcione para tener más señal no !

This thing is powered by hopes and dreams, aka it doesn’t work.My cubicle at work gets terrible reception, but the hallway just outside my door has just enough signal. I had hopes this could pick up and pass the signal across the glass of my cubicle wall. No improvement in any testable manner.It’s also not powered by anything. Not sure why that didn’t click with me when I purchased this.

Product has strong double sided tape easy to put but the only this is it didn’t catch any signal my signal still poor..

Total fail.

So, if you want to know exactly how well this works... I have a little 8' by 12' cabin out in the deep woods that gets absolutely no signal inside the cabin when the door is closed. However, just outside of the cabin on all directions there is just 2 bars on my phone. I placed this antenna exactly how directed in a window (high enough for the window to still open in the summertime) and now, when the door is closed, I consistantly get exactly 1 bar inside the cabin. For me, this is a real relief because it is enough make calls, receive calls, I even watch movies on my phone. I do not have electricity out at the cabin, so it was so nice to have such an affordable solultion that didn't require batteries or electricty. But you should know that it carries the signal in at one bar less than it is outside. It is not a booster. It's more like a bridge when you can't get a signal past a wall.

No signal boost at all. Junk!!!
