Simplisafe Entry Sensor Magnet Risers | Contact Sensor Spacers with 3M Adhesive | Easy Instal for All Simplisafe Security Systems (1/4 inch - 1 Pack)

Unfortunately, a bad experience for me. The item detached from its fixed location on the patio door despite that the proper mounting instructions were followed.UPDATE: My prior review was strictly based on my own experience of the product I received, which is not representative of the condition or marketable value of the rest of the seller's products, as no mass production of any item (from any manufacturer) is foolproof or fail-safe. The seller was genuinely concerned about my unfortunate experience and issued a full refund. He understood my concerns and acted with kindness, courtesy, and a strong desire to make things right. These are hallmark features of a consumer-oriented, highly reputable merchant. Needless to say, yes, I would buy from this seller again.

Worked great so i could align a door sensor for the door alarm. Just peel and stick

Worked perfectly

For this price there should be 10 or at least 5 of these per pack. I should have been more careful reading before ordering as I assumed it was for more than 1.. based on the average SimpiSafe user likely installing multiple of these sensors at once you should consider packs of 3, 5, 10 etc.

This worked exactly as described, however for the price I'll likely figure out a diy solution next time. Works well, however.
