Easy Honda Accord valve adjustment
Great product and good quality for the price. I had a leaking valve cover gasket on our '14 Accord and thought I would check the valve clearance while I had the valve cover off. I purchased this tool ahead of time and I'm glad that I did. The valves did need to be adjusted and there are 16 valves to do. Some valves took several adjustments to get in spec and I went though the procedure twice to double check them all. The job can be done with a screwdriver and a 10mm wrench, but this worked so well and easy. I didn't have to worry about stripping the screw head or the locking nut and I was able to get good torque on the nuts. Recommended if you have a valve adjustment to do.

Great for Honda engine
It is used to adjust valve clearance for my Honda Civic 2007. It’s worth every penny as It helps to reduce my time on working on my car. The size of the valve nut is 10 mm for Honda. The quality is great. Remember to use a feeler gauge through the process to make sure everything is within manufacturer’s specs.

Gets the job done, could be shorter
This was a great tool. Strong enough, the socket fit snugly on the 10mm nuts, worked like a charm. I do have a few complaints though. The rubber handle on what you can think of as the wrench portion slides off really easily. I threw it away in the end and dipped the wire handle in Plastdip, worked great. But that part was annoying until I did that.Also, if I were to offer product improvements, the main one would be to shrink everything down by about 25%. The screwdriver, the handle, the socket. As it is, it was a bit tall for the back valves and I had to use the old wrench/stubby to get the job done. If the entire contraption was about 2 inches shorter it would be perfect.
