Portable Mini Signal Jammer GSM 3G WiFi GPS Blockers Device
Review Mini Signal Jammer GSM 3G WiFi GPS Blockers Device
After receiving the jammer, it has been tested, everything is as described, and I am satisfied with the results.
Due to the strong signal from my coffee shop, the interference distance cannot reach 20m, but this can still meet my needs.
it works! However, it becomes so hot that you will burn your hands if you touch it. The device expanded due to overheating-but it still worked. Use it 5 days a week, at least 8 hours a day. So far, I have no problems!
Here AT&T phones with weaker signals were successfully blocked. Keep it in your head. If the mobile phone reception in your area is good, this jammer has limited or no use. In areas with good cell phone signal, you will not be able to block a single room.
Very practical equipment. It's convenient to take it with you. Haha, the only downside is that the tuning switch is too small for me!
After using this mobile phone jammer, I can now sleep well.
