    Description

    I purchased these 6 months ago. They are working well. However I had new windows installed which have no openings - hence no need for these anymore. Some of them have paint on the backside - this can be scraped off or not, up to the buyer. Regardless, I recommend using a small amount of adhesive to make sure it sticks, since the adhesive it came with as not as strong now that it's been used. Otherwise these sensors are like new.
