Good Unit for the Cash

By Phillip Holmes

from Plano Texas

Comments about Digital Reference DR-3500 Instrument Wireless System:

Great unit hasn't dropped out even once and has a good range. The only thing I didnt like is the flimsy belt clip on the remote pack and the fact that the pack is made of plastic. That makes me a little nervous. Have owned it for about one month and no problems or breakage so far.
