I had a really old alarm system (circa 1980) and Brett with Smith Thompson updated my old 'radio' unit (the old version of their wireless cell unit he called it). Actually he showed me where the old analog thing really hadnt been working since about four months ago when the wireless companies turned off the analog stuff and made everyone switch to gsm. Nobody from my old company even bothered to tell me but they sure cashed my check each month!! I would highly recommend these guys as they seem to know what they are doing. Very satisfied.
Pros: updated my old analog unit
Cons: only had to wait two days for an appointment, not bad
