About this review
Blocklr has no affiliate, advertising or sponsorship deal with Keystone 3 Pro or any other platform, so nothing here was paid for. Scores come from the rules in our review methodology. A fact we could not confirm scores as the lowest tier, which can make a score lower than it deserves. If something is wrong or out of date, tell us and we will check the source and correct it.
