What the heck is a \"one-word screw batch\"? If you know the answer, the good news is you'll have no trouble installing this. Whoever wrote the instructions clearly has nothing but complete disdain for the English language. These were obviously written in some arcane tongue, rewritten when drunk, then run through a third-rate AI translator. VEVOR if anyone there is reading (and comprehending) this, for love of the great spaghetti monster, shell out a couple bucks and pay an actual English-speaking human to translate the manual properly. As for the lock itself - it works. My biggest complaint is you can't change the combination without partially disassembling it. And as others have mentioned, the combination can be entered in any order. If you reasonably technically competent, and up to the challenge, this may be the door handle for you.
