I’ve had mine a few months and found it to be great for both on and off road. I have the trail package with os mapping, which is great both on and off road. I found I’ve have now been scouring the os map and found interesting trails. I could have done this with a traditional map, but have to stop to read it. The ability to use other people’s routes is great. Have a look at garmin connect and sign up and see. I’m happy with mine, but it is alot if money.
The bog standard map that you get with the base package is useless, so budget for a new set of maps or research open source mapping.
