In my group I ride with we have 4 Nytro's with the boondocker and 2 Apex's with Boondockers.
We all had issuses last year but all are running good this year.
As stated before I also believe there are better kits out there!
But for the masses of riders just getting into boost, They are a great kit.
If you are looking to build a 2nd sled with boost, most people would opt for another brand. IMO
All boost is FUN
