First, it wasn't real clearly documented. I got a Pro and a Classic thinking I could use it for both.
Had I known I would have just gotten 2 pros and used the extra sensors for my breaker box, roughly same price.
The thing has lasted pretty well, but I've had to change the coin cell battery like 4 times. First, that's weird on its own - never had to do this in my (long) life before in a PC.
Second, every time I have to do it I get completely enraged. Why is the connector hidden away like that? It's like brain surgery trying to get the connector in. I keep swearing to myself I will solder in a coin cell holder or something but it happens just infrequently enough (every 6-12 months) that I just cuss and spend 20 minutes put the new one in when it happens.
Why is it such a hassle to get an update? I don't get it. Some updates OTA, others you have to claim "oh, my interface is slow" or some nonsense when they ask why you want a vehicle wide update? And it takes 4+ hours?
What is this absolute nonsense?
How about "I want an update because they've added new features", isn't that fairly obvious?
