Car Cellular Phone Signal Booster & Repeater Antenna 5G, 4G LTE for Verizon At&t Sprint T-Mobile Phones by Cellet

really good, you can use any app to see it increases signal strength. Works to penetrate things like walls or the car. will not magically give you internet.

Doesn't work at ALL!!! Total garbage! That's exactly where I had to put it, in the garbage. Don't waste your money! I only gave it one star so I could do a review.

This worked well however after a car accident I decided to remove the device. I mounted the outdoor Antenna onto my windshield, and during inspection after remove a clear outline of where the product was was left behind. I reached out to the supplier months after purchase and mentioned the car accident, as to maybe get some help on a replacement. They gave me zero responses and ended the conversation then.

Before I installed this repeater antenna on my vehicle, I placed the two parts together and put a small piece of tape to hold them together, as they would be on a rear glass or window . Then placed them in a vertical position as they would be installed. So I could try different locations for an optimal signal. I found no increase in signal strength in any position. In my drive way my samsung a54 toggles between 2 bars 4g lte and one bar 5g. I had no increase in speed of apps loading incoming information, calls still fade in and out.

This isnt gonna take you from no service to full service. But it took me from no service to having a usable phone. It adds about a bar or 2 of signal. Worth it. Will be putting on more of my stuff.

OK, so I got to test this thing out today which is the 28th and even though it’s cheap don’t waste your money. This thing is a piece of trash and I’m gonna change. They’re just freaking pulling in your chain so don’t order it. It was just a hillside see I got my antenna and look right across the way on top of the hill. There is a cell tower and guess what this thing doesn’t catch🤔 signals.

I use my phone to play music with the Sirius app. I have several known locations where I am guaranteed to lose connection for a short distance, maybe a half mile or so. So, I was hoping to eliminate those dead spots by adding the passive antenna. I opted to put the antenna in the center top of my front window, even though the directions say to mount it on the rear window. Make sure your windshield wipers miss it, though -- you might have to offset the antenna a bit from center if the windshield wipers are an issue. I tested the antenna on my "known dead spots" and it carried me through them. I have a couple more I want to test on and if they work, then I'll buy more of these for each of my vehicles. I have not checked whether it will hold a voice call over the dead spots. I've only checked for data. ////////////// New info below ////////// I had the opportunity to test this antenna on a few more dead zones and it didn't perform as well as it did the other day. However, it was overcast and drizzling -- that could have influenced the test. It is a passive repeater, so you can't expect miracles. I'm not going to send the one I have back, but I'm not going to buy anymore. It is marginally effective.

No boost of signal here . I live in the middle of nowhere and it sure did not help. Maybe in other areas but not here . I would say just save your money I bought it so you did not have to.
