    It's the GOAT.

    Published by T.W. on Jun 10th 2022

    It's the GOAT. The Iaso three-piece 1.75" is the highest quality grinder I've ever seen or had the pleasure of using, and it's so good that I decided to buy two. It features flawless design and machining, as well as excellent functionality. Due to the labyrinth seal, the grinder is frictionless. And the sharp blades allow for a clean grind. The inside is essentially self-cleaning. This substantial little grinder made from stainless steel is a great product. I find that it's well worth the price and that Iaso does outstanding work. I HIGHLY recommend purchasing a grinder from Iaso.

    I had a cheaper aluminum model from a different maker. It jammed up & was difficult to thread on & off. No problems like that with this stainless steel model. Smooth like butter

    Precision work at its finest! I’m familiar w/CNC produced products, I could be wrong here, but you cannot deny the quality and craftsmanship of these grinders, not to mention the medical aspect, as well. Thank you, dudes!

    The absolute best grinder out there. I bought the 1.75 3-piece one, and I absolutely love it. Expertly and thoughtfully designed and machined, the first thing you’ll notice is the *weight* of the thing from the solid steel construction. Then you grind your first herb in it...unparalleled. It *pops* the buds apart and the result is light and fluffy, perfect for vaporization. You will never go back to painted zinc alloy bud-smearing crap after using Iova. Truly for distinguished consumers who want only the best.

    I am very impressed with the quality of this iaso grinder; A beautiful piece of engineering. The company obviously take a lot care over the product and the design, even down to the wooded puzzle box it is delivered in and the accompanying personalised note. The grinder itself is top class. It has a nice weight to it, very sturdy, and the blades do a fine job of slicing up the herbs. The cut of the treads is just so that the various layers close with a satisfying lock. I spent a good while just opening...and closing again. It's a special little product and I enjoy it very much.
