Magnet Riser Compatible with SimpliSafe | Alarm Contact Spacer with 3M Adhesive | Alarm Riser - Sensor/Magnet Not Included (1 Pack - 1/4 inch)

We had a door that wasn't quite even and this raiser was easy to set up and increased our feeling of security as we do daily tasks like watching the wheel of time and cooking. Very functional and good quality.

Perfect/exact same device as Simply Safe website sells. Using Amazon is faster and easier at pretty much the same price. I’m a happy camper. Works great. I recommend the device. Easy to use and install. Durability is great, never had one fail. I bought the at this point to add onto my existing alarm. Connect as per alarm system instructions - quick and easy.

the actual product works great and serves its purpose. the adhesive on the other hand is terrible! it is a double sided tape that is not durable. i cleaned the area on my door with the alcohol pad provided before sticking it on and it stayed for a couple hours. after that the adhesive gave out and prompted my alarm to sound at 5 am. I suggest ordering some 3M adhesive or something along those lines.

Worked exactly as I needed it to

Way over priced. Poor quality adhesive, and spacer is just 3D printed, worth maybe $0.30

We recently sold our house and moved into a rental while we built a new house. I took my Simplisafe system with me and installed most of it in the rental but had a door off the master bedroom and a door off the dining room both opening outside to the back patio. As you can see in the picture there is more than a 2 inch depth on these doors. I was unable to mount the sensors until I bought these spacers. They work perfect. Hopefully they will stay up for the time we are in here but for right now this is a cheap 5 star investment if you have recessed doors like this. Great product.

These are what you expect, they are 3D printed risers for the sensors super light the adhesive is not great and doesn't feel like it was meant for this kind of use. The product does the job but I would get your own adhesive. I ended up returning these as the Simplisafe sensor work up to 2 inches apart so the hight difference wasn't an issue. They feel over priced for what they are.

Easy to install.
