You are right. Kinotakara is one of the most expensive pads in the market.
Unfortunately in this case price doesn't necessarily translate into the value of the product.
While Kinotakara is a good pad, it's availability has been unreliable.
Additionally it's wood vinegar content is less than other brands, and has less weight per pad.
One of it's ingredients (glycol) is a preservative that has shown to have negative effects on users (see previous postings on curezone).
It is important to check all aspects before you decide which pad is the best pad ......
