3 Piece Threadless FullMag - 2.2"

Had to wait 15 days for delivery to the UK but it was well worth the wait! Great build quality & perfect grind & why has nobody come up with thus design before 🤔 it's brilliant 👏
Was undecided on this or a brilliant cut but si glad I decided on the zam!!

The finish on it looks great, the grinding action is smooth as butter. Nice that it comes with extra o rings as well.

Magnetic, 3 piece, no center post and the price is A++.

Love this thing! Teeth are super sharp, the chambers decently sized, and the way everything latches together is really nice, it definitely seems well thought out. I'd love to see a larger version!

This thing is amazing. Shreds herb like butter. And no threads? You’ll definitely try to unscrew it the first few times :-)

When I first talked to Zack McCreedy, fearless proprietor of ZAM Grinders, he was very much a man on a mission. Zach believed - quite accurately - that the cannabis grinders we were using in 2018 were terribly subpar and riddled with significant design errors.

Zach's idea's were met with positive national feedback and he set off on his ambitious quest. Zach was by no means a neophyte to product development but his early projects obviously could not prepare him for what was about to take place. What could?

In the middle of the biggest project of his young career, Zach met up with an unanticipated hurdle that threatened his project, his reputation and his sanity: Covid 19. Any person developing a new product can expect to encounter plenty of challenges along the way, but "global killer pandemic" was not on Zach's checklist and not on the radar.

And the hits just kept coming until last year, when the Virginia-based ZAM Grinder was finally, triumphantly, ready to send to waiting customers. But wait, there's more. Just when it appeared the company had weathered its last killer storm, a colossal and inexplicable national shipping snafu delayed release for several more weeks.

The killer pandemic wasn't the only snag. In the course of continued testing it turned out some design principals of the new ZAM Grinder - most notably taller interior spurs to grind material more effectively - were maybe not the industry advances Zach thought they were initially.

Zach didn't get it wrong when he targeted grinder teeth for improvement; in fact, he got it totally right with one small asterisk: the ZAM grinder's all-important teeth chowed cannabis much more effectively when made shorter, not taller. Shorter teeth also allowed for a smaller grinding zone that greatly reduced the amount of time and effort required for a bud to be shredded and swept into the stash bowl. We're talking just a couple of twists here.

The end result of this seemingly small revision is a grinder that makes short work of even the dankest buds in the bag. I waited a couple of weeks to write this review because I wanted to use my own freshly cured coastal California cannabis buds, which can get pretty knobby and sticky, to test out the new grinder. It passed with flying colors.

Like seemingly everything else today, the ZAM Grinder is about 10-15 percent smaller than the tired-out silver aluminum bricks many of us have been using for decades. This is a good thing.

The shorter, smaller teeth not only grind faster but also quickly sweep prepared flower away from the platform through ubiquitous holes in the section, where it falls into the grinder's ample bottom stash bowl. Despite its slightly reduced size, the ZAM offers one of the more spacious and usable stash bowls I've ever encountered; its high-tech surface etching is a downright game-changer.

The ZAM's roomy stash section gains some of its girth from the elimination of one of the most underused features in grinders of the past: the neglected "kief catcher" screen compartment.

Catching kief with a grinder screen sounds like a good idea, but personally I've never really used that marginal feature of yesterday's grinders and did not shed a tear to see it go (basic dry sifting of leaf and flower and/or using a Trim Bin as a "desk" for all cannabis tasks will provide you with far more kief than a old grinder screen ever will).

Another notable ZAM trait we love: the super-smooth action of the grinder mechanism itself, which is so effortless I initially thought it wasn't grinding at all; then I saw the beautiful fluffy ground flower in the stash bowl. ZAM makes all this smooth happen through judicious use of a silicone o-ring in the tool's midsection. To me, these improvements alone are worth the price of admission.

Gone is the annoying magnetic center post of yesteryear. Also history: screwed together grinder sections. Instead, superior materials and precision build quality keep the sections snug until pulled apart by the user. I never realized how much screwing and unscrewing I was doing with the old-style grinders until the ZAM showed up. Thanks, Obama, that's time I'll never get back.

The ZAM Grinder's exquisite stash bowl surface etching does an incredible job of keeping ground material unstuck to itself and the bowl. When the stash bowl is emptied, kief is left clinging to the etching. This trick by itself saves more kief than any clogged screen ever could, and it all easily slides out of the bowl - when you want it to - with the help of a soft brush or the way-cool little white weed shovel that comes with the device.

If I was forced to choose between giving up my new grinder or giving up my smartphone, my only question would be, "Do you want the SIM card with that?" My ZAM makes that question a no-brainer.

No grinder on the market works better on the cannabis of 2025 than the groundbreaking ZAM. And it's all because Zach McCreedy stubbo...
