Quietest opener is going to be the belt drive. 1/2 HP openers are more than enough for a standard sized garage door.

I've read a few reports of the belts getting twisted. Is this something to be concerned about?

Also, I live in Northern New England....does the winter cold affect the belt in any way?

Thanks!!

rizzo0904 these belts don't twist. I don't know where stories like these start. Harley Davidson has used belts instead of chains for years.

I have never seen a belt twist or break, as a matter of fact I had one heck of a time cutting through one with cable cutters to shorten the operator rail once.

Thanks ya'll. I'll be buying the whisper drive this weekend!!
