This came with 2 trackers, sounded great. Set up the first one without issue, this comes with almost no instructions, go to the website. Second one wouldn't sync to my phone. I contacted tech support a couple times, tried to follow their direction, still only have one working. Perhaps I didn't explain things correctly but their responses made me think that they didn't get what the issue was. The one that does work, works well, but it comes with a little string to attach it keys, looks flimsy. But since husband is the key loser in the family at least he has a tracker on his keys. There are many options out there, not sure I would recommend this one.
