Similar to Sindy, I started 3 years ago with a Aspect 750, the 27.5" model.
The only upgrade that I did was replaced the triple crankset with a double.
Rode it for 2 years, never had any problems, and then sold it once I got my 29er.
So I will say the same as Sindy, it's a great first mountain bike. Over 2 years of riding, I was never limited by what the bike was capable of.
