Do you like the MCE? We have several..........they do O.K. but their lack of sensitivity and heavy door functions (a lot of times in buildings the first floor hall doors, being used the most are heavier than the other doors from floors 2 thru whatever) are hard to find a happy medium. In other words, the upper doors slam open a little in order for the first floor heavy doors to open smoothly. Seen the 6970s, but not much experience with them. We have a lot of MOVFR and they do really well -- easy to work on, etc.
