Review on 10Pcs Vangonee Phone Signal Enhancement Stickers 📶 - Compact Antenna Booster for Improved Outdoor Camping Signals by Abaraham Duvernot

I've used about 4 or 5 out of 10 bought! I used an exacto knife on these 4 and moved them to different places in the phone and it didn't improve my phone's signal strength at all! I even placed them in different directions to get the best signal but that didn't help either! Maybe it could help other people if the inside of their phone is made of different materials than my phone, but it didn't help my phone! I would definitely not recommend this product if someone has a phone case that is difficult to remove! These metal stickers should fit in the back cover! For me it was a waste of time and money!
