VIVOSUN 2.5" 4 Pieces Herb Grinder Black Aluminium Spice Grinder with Pollen Scraper

I’m not exaggerating when I give this product 5 stars in every category. I’m in love! The magnet is strong as hell. The teeth are so sharp, you can feel how it slices though the weed with ease. The mid-section screws on and off so smoothly, without any annoying squeaks. It’s not too big, not too small, and fits perfectly in my hand. Not only that, my fingers don’t ram up against each other while I’m grinding, which was a big problem with my other grinder. The kief collector is quick to build up kief, and easy to remove from the rest of the grinder. It’s very aesthetically pleasing, and works just as good as it looks. I also got one for my best friend, and she loved it just as much as me. A perfect gift for yourself and others :)

I am a medical marijuana patient and this grinder makes prepping my meds super quick and easy!! Light weight design, ergonomically correct and the magnetic lid is a cool feature too! Very happy with this company and all the great products they have.

The grip makes it so easy to grind, and so far the gliding action is great as well. All the pieces come apart and go together without impedment.

This grinder is awful. For the first 2 weeks (maybe less) it was fine but very quickly it gets clogged up and starts being unable to turn/grind. I’ve already had to scrub/ clean it a bunch of times and even when it’s clean the grinder will not spin easily. The paint chips off the sides and the metal is soft so it’s scratched up already. I’m aware if you grind sticky buds this will happen but I didn’t expect to need a new grinder so soon. My last grinder was like $10 at sketchy shop and lasted years, this one didn’t even last me the month. Also, the bottom sucks at catching keif, it all piles up in the main compartment. If you smoke smoke don’t bother with it. Trashing this.

I read another review for this grinder that stated that metal shavings have turned up into ground product. Due to the plethora of good reviews for this product, I decided to give it a try.First few uses: saw a few small flakes fall into the main chamber. I caught it before I had used anything, and chalked it up to being a fluke. I actually ended up putting the o-ring from the kief catcher under the plastic washer/bushing in between the grinder lid, and second chamber... trying to prevent any of the teeth from catching on eachother (due to poor fitment).This seemed to work fine for a while... but now I am seeing metal DUST layer the bottom of my kief catcher. It has collected off of the cheap press fit insert (with the holes) on the grinder.This is flat out unsafe. READ REVIEWS BEFORE YOU BUY THIS PRODUCT. I would have been much happier with a less "pretty" grinder that actually functions.

The old Poke-ball grinder we had has lasted well over 2 years, but it was beat to a resin pulp. So, I decided it was time to replace it. After looking around, all over Amazon for a good grinder that would last and NOT hurt your hand like the Poke-ball grinder does. This one was perfect!Not only does it have groves all around, which make it really easy to grip and turn. It also does a great job of grinding up your herbs. It has a really handy extra large catching area, which doubles as storage for already ground up herb. It comes with a little scrapper that makes it easy to clean and get out all the sticky icky that make it through to the bottom of the grinder.The blades are sharp and tightly calibrated to grind up your herbs really nicely.The Green one looks really awesome and very durable. The magnetic lid stays on very easily without causing any issues with twisting to grind up the herbs.I highly recommend this grinder for anyone looking for a long lasting, durable and all around epic grinder.

I first use this grinder... bam the middle grinding mechanism breaks. Never use it until now and pops. It’s trash, it looks nice, durable but it’s just cosmetic. No value as far as durability. So now I’m sending this trash back

I was very skeptical about ordering one of these because they are always shown bigger in the picture and I was afraid of it being small but this is the best grinder I've ever purchased,,really good size!..I would suggest to a friend!

When the grinder arrived, I inspected it and discovered that the metal cutting teeth had some burrs and filings left over from the manufacturing process. They were small bits of metal stuck on the cutting edges of the grinding teeth. I had to remove them with a brass brush and a pick.These filings were very small (about 0.5 - 2mm) in length and could have been dangerous if they fell into your ground up herb and you inhaled them.Once i removed all the filings (there were about half a dozen small bits) the grinder worked fine.

This is exactly what I was looking for...well not exactly I guess, it's better than what I was looking for.I have some pretty tight bud that I grind and my old smooth sided gringer along with my dry hands were having a difficult time getting the job done.With this grinder in no time at all my bowl or roller are ready for action. And the way the little tray lifts out is a great idea in my opinion.

Coming from a huge Vivosun fan, I was a tiny bit disappointed when I noticed the kief collector piece did not fit into the bottom piece of the buster. I’m not sure if I just got a dud, or the o-ring is way too large but I’ve tried everything to get it to fit and it won’t. I’ve dropped 2 bottoms full of kief trying to pick this thing up and it falls apart.Other than that this thing is a solid construction, great design helps you hang onto it while you’re grinding. In a way I’m glad my 20$ buster was a dud rather than my 150-200$ tents and hardware by Vivosun 🤷‍♂️ It is what it is folks!

This is way better than my previous buster that was $60. I use the lid to tap against the edge of the base to get the herb to fall through the holes and it does not chip the metal or coating. It takes minimal effort to grind herb because the teeth are very sharp and because of the grip notches on the outside. It does not get jammed while grinding and the parts that screw together don't get stuck either. This is an extremely good quality grinder for such a low price! My friends wanted to know where I got it and they were shocked at the price and went and bought one too.

Big, the 2.5 vs 2 inch doesn't sound much but the larger size is so much better. Works great. Got a bit "clicky" after a few month but was still pretty easy to turn. After about a year it was getting annoying to turn. I bought another to replace it as I liked it so much. Decided to try to clean the clicky one and came clean with some iso and works like new again. Daily usage. No teeth broken yet. For the cheap price it is an easy purchase.
