I bought this to round out all the sockets I don't have and to acquire the new ratchets. The ratchets are heavy and feel smooth, the sockets don't seem much different from the older USA versions but time will tell. Where it looses its star is the extras; the allen wrenches are short and borderline useless, similar to the ones that in self assembly packages from Ikea. The little insertable bits for the screwdriver where seem to just be there to pad the number of pieces. And for having just enough wrenches to be a halfway useless set. The wrenches are nice but redundant since if you need a wrench set this won't fill in the gaps on the set you buy but will just leave you with duplicates. If you get it on sale for 80.00 like I did then it is a nice way to get the ratchets and a 110 decent sockets along with some stuff for the bottom of the tool box. If you pay full price thinking you're getting 155 useful pieces you will be disappointed.
Great purchase but I wish the sockets were complete. You will get 10, 11, 12 and 14 mm sockets. There will be a few that are not part of the set.
This has been an awesome tool kit it has most everything needed for the home mechanic to do routine maintance.
