    Finally something of Quality

    Published by RJB on May 11th 2021

    Choice of material (alloys) matters, and this Stainless Steel Grinder trumps any anodized aluminum out there. Most notable differences: lack of sticking or needing to clean; typical grinders start sticking after 15 to 20 grams worth of use and tend to get worse over time leading to jams. One of the easiest grinders to turn as you work through plant material. The Kief catcher is perfect for using most with every grind while maintaining a crust that can be scraped down whenever you want a little more. The output of the grind could be better (i.e. does not rate the highest for breaking up small hard buds) as a future enhancement, but hands down this is the grinder I would buy if I smoked daily or wanted that unique piece that no shop has.

    I love the weight and size of this grinder. Also, its very sharp teeth do their job quickly and efficiently.

    Very good, nicely machined. The double walled rim is a good idea.

    As a machinist I love this thing. Every edge is perfectly broken, the surface finish is great when you hold it, and when surfaces contact each other they glide. The fillet on the catch piece fits my finger perfectly when I scoop out a pinch, and the multi-start threads make it so it easily screws back together without cross threading, and with a single twist. The design of this grinder is excellent, and the execution is spot on. I don't know if the general public cares about all of this, but I wanted to make sure whoever is sitting in front of the lathe turning these out knows that their work is appreciated.

    Best grinder made

    Published by spkoller on May 17th 2020

    The iaso grinder is superior to inexpensive aluminum alloy grinders in every way, plus you can avoid breathing toxic aluminum particles and fumes that can cause serious health problems.

    I kind of like it but they sent me a 4 piece

    Published by Ed on Mar 23rd 2020

    I ordered a 3 piece but received a 4 piece grinder. I contacted customer service but got no response. I kind of like this grinder and the build is heavy and durable but I wanted a three piece grinder like I had ordered. The gasket should be rubber instead of plastic which has worn out with minimal use and cleaning. 2 stars because I received the wrong product. Overall I like the functionality and want this, but the 3 piece version.
