This page uses affiliate programs, including moshimo, Rakuten Affiliate, and A8.net, to introduce products.
About the scoresThe scores are calculated mechanically by applying the criteria table at the end of the page to figures published on the manufacturers' official pages and manuals (and on retail or comparison pages where an official figure was not available). We call it the "Spec Score".

We could not find a Japanese official site or official spec page for BONTEC, so the figures for this product come from the Amazon retail page (the same ASIN as the link in the earlier article).
