★★☆☆☆
At very best gave half (50%) of advertised reduction
Didn't work well out of the box with a 2Mhz wide 2.4G signal. So I/we measured the shielding performance in the lab. How you wrap the signal generator makes a big difference. Rolling the wrap around generator tightly over and over (imagine a burrito wrapped in burrito-tortilla wrapped in another burrito-tortilla ... etc) at very best gave half (50%) of advertised reduction.
Feels cheap, not like military anything.
Bought a Ramsey RF isolation enclosure.
