“This Ooze hot knife worked great on my Puffco Plus battery but it did not work on my Cresco & Kangertech 510 thread batteries. Very odd.. I’m thinking maybe it’s an amp/watt issue with those particular batteries? From my experience I recommend buying an Ooze battery to pair with this hot knife or purchase both together as one unit. I’ve now ordered an Ooze Slim Transparent Series 510 Battery to use with this hot knife so I don’t have to beat/drain the battery on my Puffco Plus. Overall I’m happy with my purchase and how this thing functions and performs, I just wish it worked on all 510 thread batteries which clearly it doesn’t. 4 stars for that reasoning.”
