I decided to upgrade my garage opener to the Craftsman 3/4 HPS Ultra-Quiet Belt Drive and after first use I feel like I made a great decision. This garage opener is beyond quiet and opens/closes very smoothly. The sensors are very accurate and can be seen in direct sunlight from several feet away. I have used the remote to open the door a block away and it registers on the first attempt. The automatic closing feature has been put to use when I forgot to close the door when I'm in a rush. The back up battery has come in handy when my power went out last summer and I was still able to retrieve my car from the garage. I'm also impressed with the accuracy of the temperature reading, but the clock appears to slowly lose track of time over the course of 4-5 days, which can effect the garage open/close timer, but I don't use it so it doesn't bother me. I would definitely recommend the Craftsman 3/4 HPS Ultra-Quiet Belt Drive Garage Door Opener because it very quiet, registers commands on first attempt, and has a back up battery system.
