Review: Perfect for Ring Alarm contact sensor replacement! - These magnets are VERY strong... it's hard to pry them apart! They do come with a plastic spacer between each magnet which makes separating them easier. I bought these to use with my Ring alarm system as an alternative to the magnet in the contact sensors used for doors and windows. This allowed me to use this magnet instead of the ring magnet with the plastic cover in areas where the cover does not allow the sensor to fit. As you can see in the picture this makes it possible for my double hung window to slide past the magnet so I can arm both the upper and lower sash with a single sensor. The adhesive strips include worked perfectly too. You can also use these as an extra sensor for protecting a window that you want to leave slightly open when arming your system! Great price and worked so well I bought more for my Moms house! You can see in the picture how much lower profile these magnets are than the ones that come with the sensors.
Review: Strong Adherence with Non-scratch Surface - Impressive strength in a small magnet. Outperformed larger, flat magnets. Have not scratched surface. Reasonably priced.

### ⭐⭐⭐⭐ Magnets are good to go.
*by J***B on February 28, 2025*

Magnets are nice and strong, and will do the job I bought them for, but the foam tape is a little on the weak side for them, have had a few fail to hold in multiple ways, had the sticky part of the tape fail from the magnet side, the sticky part fail to hold onto the plastic box. And the foam part of the tape fail and separate with the sticky parts still attached to both the plastic box and the magnet. Project. Used 4 magnet's to the plastic base that holds a 20v tool battery. Then the magnet's hold it to the side of a metal toolbox. I added some craft foam strips in between the empty spaces of the magnet's that is just a bit higher than the magnet's. It squeezes down when attached to the metal toolbox, and prevents it from sliding down the toolbox. And yes I did prep and clean both the magnets and the plasticbox, to give the foam tape the best chance to adhere. Will just have to get some heavier duty type tape.
