    Best Grinder Out in the Industry

    Published by Zachary on Mar 13th 2023

    I've spent a lot of money on many different grinders throughout my years and this is hands down the best available product in the industry. This grinder is built to perfection. You can feel the care and quality put into this product, all the way down to the little wooden box it arrives in. The grind is so smooth and leaves your herb with the the perfect consistency and it does not get jammed up! It is also reassuring that this product is made in the USA and is Stainless Steel. I used to go with the industry standard which usually is just coated aluminum. After using this medical grade stainless steel grinder, it kind of makes me cringe on how much aluminum and paint shavings that have probably ended up in my herb over the years. Long story short, buy Iaso grinders. You wont regret spending a little bit more on a product that will last you forever.

    3 piece stainless steel 1.75 magic

    Published by Allison Kidd on Oct 8th 2022

    So I was set back by the price but after spending more on grinders that didn’t work I went for it. I was NOT disappointed. I wish I would of gotten a larger one but this one works great too!

    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.

    Three piece grinder

    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.
