Well bought this out of the Hobby king USA Warehouse and I like the fact that it's light and convenient to carry since it has a storage area for the bits in the handle and that it has almost perfect knurling that isn't so sharp that it starts to bug your hands after using it for a while . I do have 2 complaints though the bits are not the standard 1/4" size hex that I like to use and the finish scratches off pretty easy .
In short makes a alright main tool but I myself would use it primarily for its great mobility and use it when Im away from home.
