Seemed like a good set, until...  I received it.  The adjustment screw shaft on the case back wrench was stripped, and the nut was not bored round either.  Someone had to have noticed this since it was assembled at the factory at some point.  It works fine until the nut goes out of alignement and then... stripped.  The other items in the kit seemed okay, if very cheaply made, but we're talking Chinese krap here after all.  I returned it.  Now I need to find a kit I can trust.

Don't waste your $$$.  You can't trust their quality control.
