I bought the company's Laijake with me when I was in training school.
Side Protector (K302S, hereafter referred to as the predecessor.) I've been using it for about six years now.
The cracks of the deterioration of the urethane material have become noticeable and also the cracks in the surface of the material have been removed
It seems to have hardened and cannot perform as it should, so I updated it with this product.
First of all, it's much more flexible than its predecessor. Compared to year six, I'm not sure... Or so they might think.
I don't know, but it's probably softer and more flexible than its predecessor when it was new.
In addition, it is difficult to put in the holder part in the previous generation, and it is unstable after putting in, and it is easy to pull out.
When I was walking, I was told by a person walking behind me that I could avoid losing it.
There are no more rounded corners or shapes that don't contribute to flexibility.
In addition, it is now moderately small, so
It seems that the worry about the slip out of the Holder is considerably reduced.
(I can't tell you exactly what I'm doing because I'm putting it in the holder section that was extended by the size of the previous generation...)
But this flexibility and size feeling means that it has a protective performance equivalent to CELevel2.
I feel the progress of the times very strongly.
How about updating your old Protector periodically...?
