yep they work... not much more i can ask of a tool. i don't need all the different sizes in this set so i probably should have ordered one of the smaller sets, but if the other sizes are needed then i have em so yay.
You dont often need this tool but it is a must have when adjusting the valves. My friend who is an auto mechanic was jealous because this tool had a great number if different sizes than the one he uses for his job.
made of solid material .every gauge for you valves or anything you need to check that requires the use of feeler gauges . only grip was the packaging ... plastic was broken open but no damage to set . would buy another other one
