We are a house divided, husband has android and I have apple. If you do not have an apple, tile is the reliable gold standard for android. These are exceptionally handy for commonly mislaid items- my husband uses them on his keys, and I have used in my purse before. They do not seem quite as accurate in locating as the apple products, but if you are just looking to ring your keys in your house, they are good enough. I prefer the apple products for pets or cars- items likely to be stolen.
They are durable and past products by the company have lasted roughly a year to 18 months before giving up the ghost.
