haa0012 's Japan Review

I bought this because I was feeling that my carbon shafts were loosening easily. I should have tried this earlier, the loosening is almost non-existent and not bothering me at all.

I use aluminum shafts and this product is a necessity.
Without it, the shaft would be loose and stressful, but by putting it on, the looseness is reduced to almost nothing. Plus, there are so many rings that if I lose or break one, I can replace it right away, thank goodness!
Also, the included metal parts allow for smooth attachment to the shaft, so I think it would be convenient to carry the rings in a small ziplock or similar container to make it less bulky and easier to use!

This is a must have for me as I use metal shafts. Without it, metal shafts loosen quickly and I can't concentrate on my game...not to say that I can't concentrate on my game, but it is a hassle to re-tighten it every time. It can also be used for nylon shafts, so if you are worried about loosening, why not try it?

It is good because it comes with a tool that is useful for attaching O-rings.

It is easy to attach just by having this.

We are nervous people and O-rings are very useful.
Even nylon shafts work well.
Of all the included instruments, this HARROWS metal one is the easiest to use.
Recommendation.

This tool is very useful when fitting O-rings to loosen aluminum shafts, etc.

I am clumsy with my hands, so this tool is helpful.
I have also found the O-ring to be properly effective.
When using metal shafts, they often came loose and I had to re-tighten the screws every time I pulled them out of the board, but after installing the O-rings, I no longer have to worry about that and they are less likely to come loose.
By the way, the plastic shaft does not loosen so much, so it is not a problem, but I still felt that the O-ring makes it even more difficult to loosen.

Smooth installation and removal of O-rings eliminates stress.

This is a tool that is not often used, because it can be attached by simply inserting the ring from the narrow end of the shaft (flight side) and turning it in the direction of the screw.
If the shaft has a special flight fixing structure, it is not possible to insert the ring from the flight side, so this tool is very useful in such cases.

I would like to have this item because it seems to prevent the shaft from loosening and I am very concerned about it clattering after I get into my stance.
