If you build mostly Technic models, this is really good to have in case there are pieces missing in the kit. Fast shipping, great price!

Nice and Fast

Even better if paired with motorization kit

This is an ok replacement set. The plastic is light weight. This is more of a random grab of gears. I bought it for the axle differentials, I should have looked closer. While there are 4 differential carriages there are not enough gears to use them. Only one. The chain is just barely long enough to use with two gears. So I am not impressed with the kit but will use it.
