Chamberlain b550 review

So, does the Chamberlain b550 Whisper Drive 1/2-HP Belt Drive Garage Door Opener
live up to its name? Read on to find out more.

Is it Really Whisper Quiet?

It would be hard for any garage door opener to really be whisper quiet when lifting a metal door that weighs several hundred pounds, but the Chamberlain b550 does an admirable job. The real “whisper-factor” kicks in when you compare this system to a traditional, chain driven garage door open. This model uses a belt driven system that is much quieter than any chain driven system available. If you’ve dealt with a noisy garage door opener for years, you really will find this unit to be “whisper quiet.”


Powerful Performance

So, now you know that the Chamberlain b550 Whisper Drive 1/2-HP Belt Drive Garage Door Opener is quiet, but that doesn’t mean a whole lot if the motor isn’t up to the task of opening and closing a heavy garage door. Chamberlain hits the mark again when it comes to power. This model features a high-powered, ½ horsepower motor that is strong enough to handle standard garage doors with ease. It uses Lift Power System, which is more powerful and highest lifting capacity compared to the other brand ½ power class.

Like the proverbial “Gentle Giant”, this unit has plenty of power and doesn’t make a lot of noise. That’s a pretty handy one-two punch combo for any garage door opener to possess.
