【L-Style】GOMU 's Japan Review

Elstyle, you've made one hell of an invention!
I love it.
They don't loosen at all!
The disposable thing is a bit of a stretch, though.

If all you are looking for is the claim that "the shaft will not loosen," then existing O-rings are more cost-effective, and I don't think they are any different in terms of effectiveness.

However, this item has a big advantage that differentiates it from those O-rings.

If you have used barrels made by overseas manufacturers, you may have experienced that there is a gap between the barrel and the shaft when you set up an el shaft and an overseas barrel, and the shaft may be shifted.

This is probably due to the slight difference in the diameter of the threads between Japan and other countries, but this product fills the gap and solves this problem to some extent.

I know that this is a small error that I don't think will affect my playing, but if you are a nervous person like me who can't help but be concerned about it, this is a must-have.

I'm using a carbon shaft and I've been waiting!
I can already feel the GOMU body filling the cavity of the barrel threaded hole and it is already tight when turning the shaft.
It is now completely fixed and I can throw more rhythmically than usual.
However, minus one point for the fact that it is disposable, even though I don't change the setting much.

I use it with carbon shafts.
It is very tight when fitting, but it does not loosen at all, so there is almost no stress. However, unlike O-rings, once the GOMU is inserted, it is pushed in the back of the barrel, so it is a little troublesome to take it out. And it is not suitable for people who often change the darts setting because it loses its effectiveness when it is removed from the barrel.

Advantage: It doesn't loosen. No sign of loosening.
Demerit: Need a new one every time you change the setting. A little bit of trouble when taking it out of the barrel.
Evaluation: If you are satisfied with the existing O-rings or if you check the looseness frequently, you don't need this O-ring. However, I recommend using it for those who use carbon shafts. If it is even a little bit loose, the probability of the shaft breaking increases dramatically...

I tried it on something other than Elshaft and it worked just fine!

Stress is drastically reduced. The shaft does not sag at all. It is disposable, so if you want to try different things, you don't need it, but if you have your own set up, you should definitely buy this product.

This is especially good for those who use L-style carbon shafts.
It really does not loosen up.

With the O-ring, the ring protrudes between the barrel and the shaft, but with the GOMU, it does not change the appearance and prevents the shaft from loosening.
GOMU prevents the shaft from loosening without any change in appearance.

Since the GOMU cannot be reused when replacing the shaft, we recommend it to those who have already decided on the setting.
We recommend it to those who have already decided on the setting.

It really doesn't loosen up!
However, when inserting it, it may be tight and difficult to insert depending on the barrel.
I have used it in 3 different barrels and each barrel had a different ease of turning the screw.
However, once it is inserted, it is almost impossible to loosen.
I am very concerned about the looseness of the shaft, and it causes me a lot of stress, so I highly appreciate the fact that it doesn't shake at all.

I have an image that it is quite a struggle to get it into the barrel when used with plastic flights.
It doesn't loosen, but there is a sensation of loosening when used with plastic.

With carbon, it goes in easily and there is no loosening sensation.
