the set looks good enough. I bought it specifically for the smaller sizes to accompany a set of small M-bolts, nuts and washers. However, when I first used one of the smaller wrenches, it turned in the head of the bolt as if worn out. I dug up a used wrench of the same size I was trying to salvage and he tightened the bolt with no problem. Needless to say I will not be buying this set/brand again and will be looking for a quality medium sized wrench set in the near future. "You get what you pay for" haunts you from time to time in this world of cheap imports, but not always as there are amazing deals on Amazon.
