The KFL+ has been out for a while so there's a lot of really good clones. The v4 hasn't been out a month yet and it's more complicated than the KFL+ or 3.1. I have 3 EHPro's (2x KFL+ v2, 1x KFL+) and 2 Infinite clones (KFL+ v2 and 3.1). The EHPro KFL+ v2's are the best ones and I've heard more than a few people say it's better than the authentic. That held me back from buying an authentic.
Nope. I bought them as backups for my VS
dna 30 and see if it'll work in the Hana mini clone I just got. I'm not too crazy about the 18490 (almost definitely a fake AW). I'll have to solder connectors to the battery and
mod.
