These are very well made and have that nice brownish-gunmetal anodized finish that matches most other aluminium 22-series parts from TLR. I've seen a lot of people on our favorite forums complaining that the 22 3.0 didn't come with these out of the box. I don't care: the stock plastic hexes are not only fine, but they are lighter (so you stock guys will probably want to stick with the plastic.) However, I have these aluminum hexes on both of my 22 3.0 buggies because they are more convenient when changing tires. Of course they are stronger and also look cool for the 5 seconds you have your wheels off, but the big benefit is really in the convenience.
