My personal experience is value for money is great but back up for spares is very bad. Depending on what you're going to be doing with it, it's always in the back of your mind that if something goes wrong it's a nightmare to repair.
I've done the razor rc brake mod as it was much needed, had no bother with servo saver or suspension arms(yet) but I haven't done any serious bashing with mine, the body has taken a lbit of damage due to being on its roof/spoiler a lot but that could be bad driving I guess.
