I wanted a small grinder to complement my dynavap and this one hit the nail on the head. If you're also looking for a compact grinder, look no further. I researched all of the stainless steel grinders on the market. This one is the best. There are many tiny design details that iaso doesn't mention in the product description: a CNC'd channel in the top chamber prevents flower from spilling out, razor sharp teeth, quarter turn bottom chamber for quickly opening the bottom without the threads getting stuck, rounded interior bottom chamber for easy cleaning and loading, etc. The price is fair. You get a quality grinder that produces fluffy flower, dead easy to clean, made in USA, and you're supporting a great company. I think it says a lot about them that they don't even bother making aluminum grinders. My only advice to improve this model further would be to make a threadless version but honestly that's a nitpick. If properly cared for this grinder should last a lifetime.

Excellent travel grinder. Extremely sharp and smooth grinding. Perfect grind for dry herb vaporizers.

I love these little guys! Perfect little travel grinder, perfectly machined, perfectly effective. A little jewel of a grinder for the person who wants a grinder that goes anywhere but doesn’t take up much space. They are so good that I sent two to friends as Xmas gifts. Stick it in your day pack with a one hitter and an eight and you are good to go wherever you are! Be aware that this is a small grinder…If you prefer to grind larger quantities, the 2.5” three piece grinder is the one that will end up living on your coffee table…either one will last a lifetime! Merry Christmas to the Iaso team..you made Christmas shopping easy!

I've been a daily smoker for over a decade. This is the best grinder I've used. I love the size, the weight and the Stainless Steel. I wasn't initially 110% convinced by the labyrinth seal design because of how it diminishes the grinding area, but it's growing on me. It makes grinding smoother and ends up serving almost like a little kief catcher. I still have a lot of years left, and I think a one hitter, a lighter and the Iaso will be my setup for life.

I guesstimated the dimensions and so this grinder is a little small, but it’s leaps and bounds above whatever you’d buy in a store! Overall I love this company and their products

It is small, but the 1.75 grinder is very well made. If I only had one grinder, I would purchase the 2.5 grinder. It doesn't sound like much, but the extra .75 of an inch makes the larger grinder more productive.

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.

Unbelievable product. Stainless Steel is safer than Aluminum. Super sharp will last forever !

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. 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.
