Query: Well worth the price...

I have now been using the Chamberlain garage door monitor for ~6 months and it works great.I have a detached garage and the base unit works anywhere in the house. I really wasn't expecting the range to be that good. The only other worry I had when installing it was having to reapply tape to the back of the sensor unit on the garage door, but to my surprise it has stayed in position now through extreme temperature variations (from -20 F to 95 F).The only reason I didn't give it a 5/5 is because I agree with some of the other reviews, aesthetically the design could have been better...
