Yeah, that's the theory except when Radtel send you a replacement bare radio to replace the original stone deaf version I bought - excitement, then disappointment to discover it is another deaf version one!
I did query it and they replied with "please send us a video of it not working.......blah blah", same as the first fiasco, no apology, nothing!
I decided not to bother, at least I have two partially working 950 Pros, but I am done with Radtel, other brands from now on, if and when I need anything new,
