Masterdam Grinders 2-Piece Anodized Aluminum Herb Grinder - Large 2.5-Inch Purple

Excellent 2 pc grinder, just what I was looking for!Can’t stand the nonsense 4 pc grinders that never allow the herb to pass thru those little holes. This one is great, perfect size and very smooth action. Only reason it’s not getting 5 stars is because the outer aluminum is kind of rough. It’s already knurled so it can me smoothed out a little more and you still get the desired grip.UPDATE! 4/8/18Standing in my driveway with one half of the grinder in my hand, my truck door bumps it and I drop the grinder half and it proceeds to roll under my truck, pops out before I could get around to stop it and out the driveway down the hill and picked up so much speed I couldn’t keep up. GONE, couldn’t find it and I looked for 2 days. 😡😡😡

This grinder doesn't do anything close to a fine grind! (maybe on super dry bud, but whats the point) end product comes out looking fluffy and scrappy.Theres no nylon gasket between the 2 pieces causing metal on metal friction and a dreadful af squealing squeak now and again.This might be ok for rolling up, but no good for bowls or vaping. I wanted to get away from the plastic grinders with teeth that threaten to break off into your consumables...but the grind is better.I'd return it but I'm not sure of the legalities at this point and I've already tossed the packaging.On the positive side of things the grind chamber is very spacious, and the magnets seem stable. The teeth are super sharp. The fact that its a 2 piece is nice, and was a driving factor for me, i just wish it did a more thorough job.

It for my opinion the best grinder brand. I don't know where they are from but they are very serious. I have two of them and they do the job perfectly. The teeth are very very sharp and you can't even feel the weed being grounded. Very small because the pocket size but very useful and enough for my needs. Thank you Masterdam because on amazing there is almost only Chinese product in very poor material. Oh I forgot the magnet is very powerful and it is something you might miss with the others.

Love the product! Works great only 2 or so twists and your product is ground! I do however give it only 3 starts for ease of use because before use you have to make sure you maticulously clean it out! There was 6 or 7 tiny shards of metal in there and that isn’t something I want to consume! Other than that I’m loving the purchase.

this product is a very nice grinder ,light ,the cutting edges are very sharp,grinds first full turn ,i would buy this product again but as it is made really well and sturdy I believe it will last a life time unless i lose it.

What I expected. Single chamber herb grinder. The instructions ask you to check the grinder before use for any metal chips or shavings left over from the manufacturing process; initially, this was a turn off for me, but I inspected the two halves using a wooden tooth pick and was impressed by the craft of the object. I can tell precision was a must for the manufacturer, and I appreciate the care taken to assure a quality product. I'm ultimately glad too have purchased this product rather than one of inferior quality.

Well made, a little hard for large hands, very good grind!

The product is fine, but using it with sticky, resinous materials presents a couple of issues.First, it is a chore to clean. That is not unexpected, but if not kept scrupulously clean then grinding performance will suffer, and it will bind.The biggest problem is that its small diameter requires a high degree of grip strength.I will have to modify it by attaching something like "wings" to provide additional leverage - perhaps a 3" piece of 1" aluminum angle top & bottom.Pocket-ability is not a consideration for me.
