This was my first purchase from DescBoost, and I was impressed by their communication and website value. At first, the price seemed high, but after comparing the cost of separate GSM blockers and WiFi interceptors, this option turned out to be much more affordable.
The cellphone blockers purchased for the company's large conference room works well in a space of 500 square meters.

We installed a cellphone jammer in our confidential meeting room, and it made a huge difference. Before that, we were always worried about hidden recordings or leaks — it was hard to speak freely. with the signal completely blocked, the atmosphere is different. People are more relaxed and open, and we know our conversations stay private.

The cellphone blockers purchased for the company's large conference room works well in a space of 500 square meters.Before installing the signal jammer, my employees were constantly looking down at their phones during meetings. I felt disrespected and a bit frustrated. But once the signal was blocked, everything changed — they became focused, attentive, and fully engaged in the discussion.
