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.
The ratchet would not hold the sockets due to a bad ball/spring.
Nice open pocket too add must have Allen wrenches.
