Negative Positive
Title: Good; could be better.
Review: I have two of the whisper drive openers...my only complaint is the quality of the spring clips used to secure the reverse sensor wires. You have to insert two wires into each spring clip and while the first works well, the second wire can be a challenge as the clip doesn't always secure the second wire. A beefier spring clip, or a clip for each wire would be nice...wasted a lot of time with a mini screwdriver trying to get the second wires to hold...have also had the wires come loose over time due to unit vibration and when that happens, you can't close the door until you fix the problem.
