taa0011 's Japan Review

Metal shafts are used and are essential to prevent loosening.

When tightened, the rubber end does not come out of the gap between the barrel and the shaft, which gives the impression of good quality.

And since the o-rings come pre-installed on the mounting fixture, they are ready to use when you need them!

It works so great that I think it's a must for aluminum shafts! Just a light tightening is enough to keep it from loosening. If you are worried about the looseness of plastic shafts, you may put it on. All you have to do is to insert the thicker end into the barrel, shift the O-ring, and insert it. Well, I can see it when I look at it (laughs). It really feels good not to be loose!

I bought this because I was tired of having to re-tighten the shaft after each pitch.
The looseness of the shaft has been reduced to a great extent and I don't have to worry about the stress anymore.

I bought this a long time ago and I've been using it ever since. I bought it a long time ago and have been using it ever since.
I used to throw it, pull it out and check the looseness.... But now that I have this product, I only have to worry about the tip part being loose, and when I throw, I can just say, "Oh, no, it's loose! Oh no, it's loose! I don't have to worry about it anymore!
I thought that installing one part might affect the weight and balance, but it's not to the point where I'm concerned.
It's a must for metal shafts. This is a must for metal shafts. I am very impressed with the way the looseness disappears when attached to a metal shaft. When I gave it to a friend who was having trouble with a loose shaft, I asked him if he would like to try it. He was very happy when I gave it to him.
It comes as a set with the Applicator (aka bamboo shoots), so buy this first! Don't you want it? Yes, you do. It's so convenient!

I didn't know how to use it at first, but I soon figured it out.
It eliminated the looseness of the shaft and reduced my stress.
Thank you for the fast and careful shipping.

You can install it without a tool, but it is still easier with one.
As others have mentioned, it is cheaper than other companies, so I would recommend it as a first purchase.

Convenient.

I use it on shafts and 4BA converters!
I'm happy just to get rid of the looseness, less stress when playing!

I put it on all the shafts. This ring acts as a buffer and prevents them from coming off, so you don't have to worry too much about them coming loose while throwing.
I recommend it to those who want to concentrate on throwing.

I could probably install it without the bamboo shoots, what a waste! I thought it would be a waste!
But it was still very convenient.

The difference between the Harrows set and this Target set is only 80 yen, whereas the difference between the Harrows set and this Target set is 180 yen, so I recommend you to buy this set with tools for the first time.

The O-ring itself is a useful item that keeps the shaft from loosening, which is a concern if it loosens every time you throw it.

It really eliminates the looseness of aluminum shafts!
