Apparently Spot has a new product in development to directly compete with the InReach.

Yesterday I took my first flight of the year. Before takeoff I turned on the device, started tracking, and shared my flight with my wife. Everything seemed fine.

When I landed about 3 hours later (it was nice to be back in the air, but the day was not great), I tried to power down the device, but the screen was dark. On further examination, it did not send any tracking data during my flight, so it must have been dead almost from the start.

The device was two years old, and had been used exclusively for soaring, perhaps 60 flights total. When I called Garmin they lead me through a couple of tests that determined it was dead.

Replacement: $200! And the replacement device is refurbished!

The fact that they are providing a refurbished replacement is an indication that they do have a supply of failed units.

Has anyone else had such an early failure?

BTW, here is my estimate of the cost for two years of flying:

Device -- $400
Activation -- $30
Monthly fee -- 10 months at $35/month, $350
Total -- $780

Or ~13/flight

I really wish there was a comparable competing product...
