Fast delivery, relatively decent product with the splines mostly eliminating the slop of the non-splined hubs they replaced.
Note - Two disappointing aspects with this product.
1. The wheel (hex) nut is smooth on both sides, and these things like to come loose.
2. The thread pitch is incompatible with HPI/Losi/Mugen (and I'm sure many other hubs).
This means that you cannot replace wheel nuts with universally available nuts like NHX
when you lose one or want to upgrade them.
