    New sensors are much better than gen1. Much better design. Initially bought 6, but now will replace all the old ones as well.

    bought the six pack at best buy and had 1 bad one. turns out, for you to return the 1, you have to rip off all the sensor you did but up, then put it back in the box to return it. They will not open another box to take out one good one , and put the bad one in. the product works great I have 11 sensors .

    Better pricing than purchasing individual contacts. These work great for windows and doors, could even use them for cabinets, drawers, etc that you want to monitor for opening.

    These sensors are super easy to install. I would definitely recommend cleaning the surfaces before applying them, to remove any grit that can get stuck in the adhesive.
