I have several of them in and they are working great, the software is like anyone elses has its quirks but usually works fine. It has canned programming and you can customize almost any program to fit your individual needs.
KMC / RELIABLE use to cross produce equipment for each other. They parted ways about 5 years ago.
KMC does some strange things with this LOCAL REP mentality. Our LOCAL DDC REP is the POSTER BOY for giving control contractors a bum rap. Low balls the job , installation is messy but he HOOKS the customer for BIG $ for service and basically finishing the jobb as it should have been done intialy .
If your looking to REP someone checkout RELIABLE as well as KMC
Do a search on the internet. A year ago I was in need of an interface device, 5557 or something like that. All local reps wanted anywhere from $235 to $350. Found one brand new for $125. Seemed pretty reasonable to me. Cant recall who or where the rep was though. Look around, you will find what you want.
