They are a real vendor, I believe based out of Italy. They respond to questions by email generally within a day or two (not counting weekends) and their staff seem nice.
Some things might not be available or ship right away but they are very clear about quoting dates before you purchase which is great. They run periodic 10-20% sales on different brands, for example one month will be Hazet specials, the next Usag, etc.
I ordered a Hazet assistent from them a while back since they had the lowest price during a sale. The box got a bit roughed up by DHL and was ripped open for "inspection" and sort of taped back up.
When I picked it up from DHL, all of the hand tools were rattling around loose around the cart with no padding or other packing material. So either DHL managed to unpack it and ditch every scrap of padding (unlikely but not impossible) or Mister Worker's packing team just didn't care. Surprisingly the cart was barely scratched and everything else was ok (minus one missing socket), so I didnt complain because it wouldn't have been worth the return postage.
