Wrenches and sockets are as good as any in the world. Hazet, Stahlwille and Gedore have nothing on TOPTUL. In fact TOPTUL sort of copies Stahlwille, which is the company they consider to be the world standard. Their screwdrivers are fantastic. Every bit as good as Wera or Wiha. I've never had any PB Swiss so I can't speak to that but I do have Wera and Wiha and TOPTUL's screwdrivers are every bit as good. If it's a forging TOPTUL is as good as it gets. A lot of their stuff comes from other Taiwanese sources such as their torque wrenches and automotive tools. But, by and large, if they put their name on it it's good stuff whether or not they themselves make it. A lot of their air tools come from Kuani Gear and their digital torque wrenches come from Eclatorq. Both top of the line Taiwanese companies in their respective fields.
My problem with TOPTUL centered on one particular person who was my point of contact. She's long gone so that's one problem out of the way. The other problem is that TOPTUL is very ASIA and Euro centric and really doesn't give a **** about the American market. For example many, if not most of their socket and wrench sets, skip 18mm and sometimes 15mm. Anybody that works on American cars knows that Fords in particular are polluted with 18mm fasteners and GM has 15 and 18mm everywhere. I had to buy individual 18 and 15 mm wrenches and sockets to add to the sets that I sold so that I could sell them as without these two sizes the sets would be worthless. I fought and fought to have them change this but to no avail. They make a fantastic zero offset long box wrench set that doesn't have 13, 15, 18 or 21mm in it. They don't even make individual wrenches in this style and size that I could add to the sets.
