I am a hospital worker. By using this type of jammer in hospitals, it is possible to prevent damage to the human body caused by cell phone use and medical equipment failure. At the same time, I don't have to worry about the ringing of the cell phone that is brought to the patients at night.
So far, its operation is really very good, I hope it will be as reliable as it is now!
This jammer is said to be the most popular product here. After using it for a while, I found it really great. The interference range is very large, and there are many jamming frequency bands. Honestly, the performance of this product exceeds my expectations!
