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.

Necessary tool for valve adjustment!
I would recommend this tool when doing a valve adjustment. Instead of using 2 tools, it's built into one for easy adjustments on the fly. I did my first valve adjustment and this tool was a life saver. I think the process would have taken a lot longer without it. The tool looks sturdy and it would likely last a long time. Two thumbs up for me.
