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.

Good quality tool, but will NOT work for Honda k series
Tool appears to be well built, it fits perfectly on the valves and gives plenty of space to loosen and tighten the jam nuts. As a warning, however, the tool will NOT fit the valves on a Honda k series motor. I tried to do the adjustment on my TSX but the tool is too large for the jam nuts. You’ll need the 10mm version for the k series and other Honda motors, so don’t make the mistake I made and double check what size the jam nuts are on your engine. Even so, I am satisfied with the quality and will purchase from this brand again.

Easy to use, as long as there is clearance.
These tools make a tricky job easier, assuming the space is there to fit the tool into. What a great idea.

It works great!
I bought this tool because I saw it on videos and I’m so glad I did! I did a valve adjustment on my type R for the first time and this tool made it sooooo easy. If you need to do a valve adjustment on Hondas. Get this tool asap!

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.
