Negative Positive
Title: Good operation, very poor sensor design and service
Review: I've had this product for about two years and was generally pleased. But recently when I needed to replace the batteries in the sensor, I discovered that the very deeply recessed screws were "frozen" and I could not budge them with the very tiny screwdriver I needed. Certainly they could have designed the case to be more user friendly. I e-mailed the company describing my problem and asking for suggested solutions. I never got a response.I would not buy this product again.
Is the review positive or negative?
