It was what I expected, for the price. I have bought in Mexico the exact same ones, but with a different color and different brand sticker. They are cheap, but do their job well. We use them 6 hours nonstop 6 days a week.. And they last about 8 weeks. They are for us, disposable. The oil attachment doesnt really works.... it just easier to oil them manually. The case is ok, better that the once I previously bought. (it was only a cardboard box)... Do as most cases... the designer only thought on the initial display before purchase, pretty for the photo... Once you assemble the grinder with the male end of the quick connector and the oil attachment... they dont fit back in the box... So you need to cut holes on the plastic. we are not going to assemble it and disassemble it every single day. If you will us it occasionally.... it will last for years.... If you use it nonstop, probably only a few weeks. A lot cheaper that more renowned brands like IR or Chicago Pn... so if your giving them to employees that wont take care of them... better to purchase these ones, than expensive ones. As they will damage them in about the same amount of time. I Bought 10, and expect them to last me from July to December 2018. Once my employees destroy these 10, I do plan in purchasing more.
