    Four piece 1.75”

    Item works wonderfully and better than expected :) unfortunate that it doesn’t come in the magnetic box as advertised in every review I read before purchase and instead comes in a poorly constructed wooden puzzle box

    Fantastic grinder, but get the bigger size!

    Published by Jenna on Aug 17th 2020

    I really love this grinder, but the 1.75" size is VERY small. For such a small grinder, it holds a ton of herb (I can get 2 handrolls out of one full chamber). I love the design and the way the top just glides! My only issue with the functionality of the piece is with the keef catcher at the bottom. It tends to twist off on its own, I wish it had a stronger magnet keeping it screwed in.

    Steel grinder

    Published by Jed Snow on Jun 30th 2020

    The grinder is the best one I’ve ever had. It is a High precision product. The least amount of effort I’ve been required to grind herbs, and the best part is it doesn’t bind up at all. Long story short it’s worth spending more on this product than a $20 grinder. The cheap-o’s will start binding up after a few uses. I’ve used this new grinder about 100 times and it is a smooth as day one. Zero binding

    Supreme Satisfaction

    Published by Richard on Jun 15th 2020

    From the purchasing experience to having this wonderful piece of machinery in hand, I have been blown away by the quality IASO and their product. Customer service was very responsive when shipping was delayed and I have never been dissatisfied using this grinder. The precision of the machining and weight of the grinder make for an excellent experience. Highly recommend this product for anyone looking to upgrade their herbal milling experience.

    It’s the best grinder I’ve ever owned. Incredible craftsmanship & grinds superbly. Being made of stainless steel, it’s probably the safest grinder on the market for the medicinal cannabis users like myself who are concerned with contaminants, in our flower, like aluminum. Ever notice the aluminum smears on your hands when grinding with an aluminum grinder... I’ve experienced nothing like that using this stainless grinder. I highly recommend this grinder & compared to other grinders that I’ve purchased over the years, this is well worth the investment. I am actually considering getting a couple more. Thanks for putting together such a well made & health focused grinder.

    Well made with quality materials. But I wish there was some kind of locking mechanism. It easily opens if thrown in a backpack
