I use these sizes all the time on my import car the 10mm, 12mm, 14mm, 17mm. only wished the set would have came with the short extension. If you wait and can get this set on sale for ten dollars you really can't beat it.
Unless you can find a NOS in a smaller store, these are now made in China. The fit of the socket on the ratchet is terrible with lots of play (especially in the smaller sizes. Other stores sell better products at lower prices, even if they also are made overseas.
Ratchet was very stiff, hard to operate. Disassembled and added good lubricant. Much better but still not one of their best ratchets. Rest of tools are good. Did not come with any extension bars, needs a least a 1 1/2 or 3 inch ext.
