(Kind of spent all my money on other stuff like helmets, radios, and this thing...)
Well, If the product worked at all... see review.
Ok, to get this out of the way. It says in period of use, only tested. That is because I would never use it for anything. I have tried everything to get it to work: 3 different brands of radios (nice ones too... Like $50+ ones), all the different settings on the radios, and even tried more than one of this same product. My friend Dan and I both bought this mic in high expectations. Once we got them we ended up working on them and testing them for 2 days straight (mostly because we are poor, LOL, and wanted them to work because there would be no way we could afford another mic after this), and to no avail. The best quality we could get would be an audible mumble. Could not understand a thing. And yes, we tried placing it all over our throats with different pressures and it still wouldn't provide any results. We gave up on them. Their quality is horrible, ear piece kept on falling apart. The thing just feels cheap.
I don't believe in giving products a rating of 1, but when a product costs $30+ and doesn't do anything at all, I have to. I am writing this review to warn future buyers. I don't know if all of the company's products are bad, but this one is.
