I consider myself a relatively handy guy, relatively confident of installing most things, be it woodworking, flooring, or technology based things. In mid October of 2012, I installed a garage door opener for our 2 car garage, the Chamberlain WD962KEV Whisper Drive with a battery backup; it was a relatively easy installation and only took a couple of hours by myself (although I did need someone for a couple of minutes while I was holding the opener and juggling a few things). Keep in mind, I had never used a garage door opener, nor installed one previously. I had to do a lot of research into garage door openers looking at what features were available like battery back-up, how noisy it is, what safety features and anti-theft features are available, the warranty (lifetime motor warranty), and the basic stuff like what's included like car remotes and outside remotes, the HP to lift the door.
There were a couple of models I was considering based on different price ranges, and while this model is more of on the top end, it had everything I wanted and I wasn't going to settle for something I didn't like, especially if I had to deal with it every day!
This model was absolutely great, it has a battery back up which you don't realize how nice it is, until you need it. --Recently a transformer blew in our neighborhood and left 300+ people without power, I left the house without a single trouble because it had a battery backup, and it was wonderful... and I felt like a million bucks because I didn't have to worry a single bit or lift a finger--
Our garage is also next to our spare bedroom and I would hate to have our guests wake up rudely because I'm leaving for work, and because this drive is so quiet, I'm not afraid one bit. With the garage door well lubricated, honestly, I hardly hear it, unlike ALL of my neighbors garage door openers.
My wife and I are also worried about someone "hacking" into our garage because the codes don't change on some of the cheaper models, but not the case here. With this opener you have "Security+ 2.0 anti-burglary technology, which assures that a new code is sent every time the remote control is used, and PosiLock theft protection, which keeps the door locked once it's closed. A manual release handle allows you to open the garage door in case of a battery failure" The manual release we also put a zip tie around so no one with a coat hanger can unlock it from the outside (a proven safety tip). Also, it auto-closes within a few minutes in case we forget to close it for some reason, but don't worry, it has sensors to make sure no one is directly underneath it. It also comes with an outside remote which is wireless and two car openers.
It was a wonderful purchase and currently, amazon is having a gold box deal so, you can snatch one up for only $190, here and with the money saved, you can go and buy their surge protector for $10 to protect it from everything up to a lighting bolt strike.
