Don't waste your money - I eagerly preordered through their Kickstarter campaign and have been thoroughly disappointed with the final product. A couple of the many negatives:
- Extremely limited range; it's connected using Bluetooth, hence if you're tile is beyond the 15 feet or so BT range from your phone you're out of luck. Relies on everyone having a Tile and your car being within 15 feet of them in order to function.
- Low volume; the beeps the Tile generates to notify you of its location is comically low - you pretty much need to be right up against it to hear, which kind of defeats the purpose
I'd check out the reviews on the App Store, you'll see some of the other common complaints and the terrible overall rating.
