very cheap

I compared a lot of sites before buying jammer, topsignaljammer has a much lower price than other sites and the quality is very good.

Shielding works well.

I bought it and received the package a week later, it's a plastic case, but that doesn't prevent it from dissipating heat, and the device works well.
