I used my TrakDot late last year on my IAD-SFO-SEA-LAX-IAH-MUC-HAJ outbound. Luggage got stuck in MUC (Munich), filed a claim right away at HAJ (Hannover) and went to the hotel. Got alerted when it landed at HAJ, and went downstairs to the lobby about an hour after it showed up in the vicinity of the hotel. It had been delivered, but they didn't even have a chance to call me yet. Forgot to turn it off, went with me down on the ICC train to Munich, which was cool to see on the map. Batteries died after 6+ days.

This year it went with me DCA-JFK-SFO-HKG-NRT-HNL-EWR-IAD. No service in Japan (as explained on their site), but otherwise performed perfectly. No problems on my other short trips thru CLE/DEN/DFW/LAS/IAH/MCO/ORD/YYZ.

For added protection of the unit, I keep mine in a bubble-wrap mailer. Also good to keep spare batteries in there.

Location isn't as accurate as GPS (up to 1/2 mi off), but easily enough for what it's made for. I bought mine with a year of service, upgraded to Lifetime when it was offered. I am very pleased with my purchase.
