Nice intercom, good sound, sufficient range, easy installation, good software. The only negative that might have happened randomly to me, because in our group we have 7 people with the same intercom, is that the cable doesn't make a good connection out of the box and you need to play around with it a bit for the left earpiece to work. I should have asked for a replacement; it's my fault because it is really a very good device. 5 stars with reservation

So far, everything is good. Very quick connection when you open it with your phone. I haven't found if it has any speed dial. That's why 4 stars. Other than that, excellent.
