    I have a bad habit of always misplacing my keys, so when this product became available I immediately ordered one. The personalized design and small size does not make my keys look bulky. The app is easy to install and use. I my jayster almost everyday to find my keys and my time is no longer wasted running around the house looking for them. Recently I had the bright idea or putting jayster on my dog’s collar when I leave her in the yard. She has a habit of getting out, now with Jayster I am able to locate her faster. I recommend this product and will be buying for the holidays as presents.

    My aunt suffers from beginning stage of Alzheimer’s and tends to hide things especially my keys. Thanks to Jayster I don’t get so frustrated when I can’t find my keys. I simply use the app and I find my keys in seconds. I have now bought several to give to my other family members. This device has brought some peace to the situation.
