HME Wireless intercom

I'm looking at the HME wireless intercom system for my small theatre. I'm wondering if anyone has used it and seen successes/failures.

 

Used a 4 headset system for a one-off audio gig at the MTCC in Tronto. They had lots of noise, and in my opinion we could've used Motorola radios with headsets instead and had the same sound quality.

It could've been the system, or the way it was setup, I'm sure they're worth a bit of the money you'd pay for them.

 

Which one? HME makes a lot of different models, both analog and digital. If you do a search, you'll find lots of comments on them in previous threads
