【Harrows】["Carbon"] has1801 25.0mm 's Japan Review

I recently purchased it and immediately installed it on a barrel to try it out.

The result...on the second day of play, the flight insert gradually started to tear.
Maybe it was because I kept throwing it without the shaft ring, but it is too fragile.

The aluminum shafts sold by the company were excellent at holding the flights in place even without the rings, so I was careless and thought this one would be fine as well.
If you are going to use this product, I think a shaft ring is a must.
I haven't tried it, so I can't say how well it works...

I tried to say it was a carbon shaft.
Sorry if I am wrong. This is a 3-piece construction, the very shaft part is carbon, but the other parts are aluminum? I guess?
It is certainly not heavy, but it is not extremely light either, and the flight retention seems to loosen relatively quickly (it tightens after tightening, but it may be difficult to adjust? I'm afraid to put it back in because it's too tight, so I just use it as it is.)

I think the coloring is cool.
Considering the price, what do you think?
At any rate, I think I will use it until it breaks.
