I have 3 of these for the kids and an M11X for myself. They have everything you need to set up a car well and excellent feel. They are much better for the kids as they are significantly lighter. Truth is there is very little difference using one of these to the M11X!
For the price, how they feel and the adjustments they are a bargain! If I didn't have the M11X and only had one of these I would not feel I was at a disadvantage on the track.
