SELLERS OF ANY WIRELESS SYSTEMS ARE MOST LIKELY ILLEGAL!!
Buyers beware! If you're looking for any instrument/musician wireless and you think that you're getting a great deal on a used system; Sennheiser, Shure, etc and it's anywhere between the 600 and 800+ MHz range, YOU'RE NOT!! These are illegal to use in the US and moreso, illegal to even sell!! The site (s) that we as musicians as shop at and try to find bargains are preyed upon by the sellers of these units who know these are illegal and list them anyway. The sites themselves don't care because they get a percentage from the sale. You can send the seller messages and report the seller to the individual site the item is listed on and they don't care. Especially ones who list their items as "Church used". You should especially be ashamed of yourselves!!
