Review Waterproof Jammer Device
When the signal jammer switch is turned on, the blocked signal will be eliminated. This is the best signal canceller
I purchased this jammer for use during company meetings, with the purpose of disabling attendees’ phones. Now, we have received full attention from everyone, and our trade secrets are more secure. The device is so powerful that we had to turn it off. highly recommended.
This jamming device suitable for outdoor use. Waterproof properties is good!
Amazing waterproof jammer! Used in prison is really good! Finally do not have to check whether the prisoners smuggle mobile phones!
Very interesting design, built-in antenna, does not look like a jammer. Waterproof function is very practical, can be used in the open air.
