Chamberlain Wireless Motion Alert System

I should have read the reviews, this product is garbage it did not last 2 weeks. The sound is low and can not be heard over the TV sound. I bought from BK Rider through Walmart and when I emailed BK about the defective item they said it was discontinued and would I like a refund. I have emailed them 4 time to send me a RMA and I have not heard from them. The battery compartment on the receiver is almost impossible to open and the transmitter light stays on and does not send a signal. When I first installed it, it would pick up only part of the time and one of my auto's it would not pick up at all.

Have installed this particular product - Chamberlin - in different environments - and it performs very well as stated - once the "learn" procedure is completed - holds the settings even after power loss - tho - with high traffic events - would recommend changing batteries in transmitter each year than wait for the " can last up to two years" time frame

I can not get them to work I went to the company website to get some help it does not have the products list at all! I tried to leave some message and can not do that.

It took me about 15 minutes or less to get it installed and working. No problems and it works great. The sensor is located about 150 ft from the house and the receiver is inside the home. It has worked every time.

I laughed when the description gave the range of service, but I knew that buying from WAL MART it could be returned easily. I added one extra sensor. The order arrived when stated. It was simple to install & it works perfectly. This is the first electronic item that I have ever bought that works as stated. Total Satisfaction. I have already told friends.
