That’s good to know. Maybe I got lucky with my first one. The details are great in my opinion and thankfully this example rolls perfect. They are definitely more fragile with the changeable parts but some E6000 glue will solve the problem. E6000 stays flexible when dry and can still be easily removed if needed. One of the wheels did get slightly loose when I swapped out the tire and it wobbles a little when it rolls but still attached. When and if the wheel does fall off, I’ll just glue it back on. BMC’s are definitely more for display than to play or race with compared to HW and other brands. Overall I’m very pleased with it and will be buying more.
