    Iaso Small Grinder

    Published by Hilary on Jan 13th 2021

    This grinder far exceeded my expectations. I was looking for a small, high quality grinder and I found this one mentioned in a “top 10 of grinders” on the web. I thought I’d give it a try and I’m not disappointed. It had the look and feel of exceptional quality, it grinds like a dream, effortlessly. The small touches like the angled storage section and the curved crystal catcher make it unique. It’s perfect for my handbag or pocket although it’s fairly weighty but that adds to its beauty. I don’t often write reviews but I am so pleased with it I thought I’d share my findings. I am in the U.K. and it came reasonably quickly considering it was coming up to Christmas and during the Covid lockdown.

    Quality Product

    Yes it’s expensive, but seriously good investment! When you hold the product, the price makes sense, exceptionally well made and performs flawlessly. Plus you’re only gonna need to buy it once as it will last a lifetime. Have recommended to all my friends.

    I love what it does but it is so small you have to re load it to many times and the lid is so thin I can't grip it to use it. It hurts to use it. You need to make it easier for old people with arthritis to turn the lid.

    1.75 Grinder

    Published by Bob on Nov 28th 2020

    Very solid, excellent grinder. Extremely well made. Works exceedingly well. The 1.75 is a little bit small for my arthritic hands, so I bought the 2”, which is perfect. Someone’s getting the 1.75 for Christmas. BTW IASO is a great company. Great customer service!

    Perfect grinder for bowls

    Published by Paul on Sep 24th 2020

    This is ‘the’ Grinder to own if you are smoking bowls, it grinds the perfect amount every time. The grinder is unmatched in quality, and can easily handle hash chunks. Overall this grinder is a keepsake that will easily last a lifetime. Pair this with a storage container for an eye stopping kit everywhere you go.

    Four piece 1.75”

    Published by Cody beiersdorf on Aug 17th 2020

    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.
