i'm an owner of their Garmin 945 LTE released over 4 years ago. I have paid the subscription since. The device is still working very well, still got an update a couple of months ago. Battery still lasts about 5 days.
I thought Grok 2 was pretty bad, but Grok 3 is actually quite good. I'm mostly impressed by the speed of answering. But Claude is still the king of code.
