Simple install, other than a couple of wires breaking below the window seals.......Not their fault...Seems as advertised

Magnets aren’t strong enough to pull contact.

Been installing wired alarm panels in rentals. Works great. Renters to hard on stuff that requires battery maintenance or is easy to touch. These are somewhat out of sight so my "handy" renters typically don't mess with them

Ordered 10 pack. All work. The magnets that come with them are very powerful. About 3/4 inch distance to close the switch. Took one and flexed the wires at the base, several times. The switch still works. So, they work perfect.

They work great. Small profile is easy to install in tight areas, but for areas where you need to drill at an angle a larger sensor would be easier because you'd be able to drill a 3/8" wire chase at an angle more cleanly through a 3/4" sensor hole. the 3/8" sensors are great, but you have to take care to drill correctly or you'll have to repair over-sized holes with caulk or putty.

The package comes with 10 sealed NC switches and 10 magnets. So far, 2 of the 10 sealed switches DO NOT respond to a magnet. With no magnet nearby, each defective switches is closed (conductive). With a magnet is nearby each defective switch is closed (conductive). So, for this order, at least 20% of the delivered parts are defective.

Had a busted window sensor. Pulled it out and ordered these because they closely resembled what I had. Tested and works great.
