I’ve been using a 1Zpresso JX-Pro for just over four years. The only complaint I have is the rubber grip coming loose after a couple years. Not a big deal, a minor annoyance. Otherwise, I like the grind, it’s easily to disassemble and clean, it seems well made and hefty.
Edit: Looks like they remodeled the grip since I purchased it. Also worth noting you can buy spare parts from their website. I just may stock up on some.
I suppose it depends on your budget. I’m not sure yet whether it’s BIFL material as I’ve only had it for a month now, but the Timemore C2 has been very pleasantly surprising. It feels well made and grinds evenly. It’s all metal so if cared for should last a long time.
