This brake lock indicator is very well made and very easy to use. I tested it today and it works as described. The alarm is very loud and will definitely deter potential bike thieves. I received an email from the company shortly after the alarm was delivered to ensure I was happy and satisfied with the product. A small issue was the length of the reminder cable. I had to stretch it to the max for my Indian Springfield bike, which is a big bike. Another 6 inches would be perfect. The alarm will remind you all I had to do was straighten the front wheel and it worked. I would recommend this product to anyone who wants to protect their bike from thieves.
