Review 5 Bands Handheld Portable Jammers All Cell Phone GPS
First of all, the delivery is fast, the packaging is neat, and I am very satisfied with the product...designed, efficient and easy to use, the product fully meets our expectations.
I just received this jammer, it looks great, the signal is completely blocked. I like it very much.
Jammers are very convenient and can interfere with various frequency bands. And turn on or turn off the corresponding frequency band according to your needs. The only disadvantage is that the frequency band switching is too small.
This product fully provides the content described on the website. The price is reasonable and the delivery is fast. I highly recommend this product to others. Thank you! I really like the jammer at this price.
Like this feature, and really have the latest design. I have bought one and it works well.
Super fast delivery. Get it in 5 days, there are also 2 non-working days there.I use it to stop the phone call from my noisy roommate, which usually lasts until 3-6 AM. It takes 5 to 15 seconds for the phone to display "No Signal". Great power brings great responsibility. Please use it in the shortest time possible, otherwise, you may accidentally block a real emergency call nearby.
