Had for 1 year - Great grinders. Even the sticky doesn't clog it up. Grinds about .5 gram per. Overfill & it locksNot great kief collecter - just sticks to side

First of all, the chamber holds a medium size piece of herb at best. Don't over-pack it or the grinder won't spin. Also, unless the leaves you start with are dry and not sticky, don't expect the ground product to ease through the tip like that. It won't. It's usually too sticky. You simply leave the screw-on cap on the tip and unscrew the chamber OVER a container or other protective surface to catch anything that spills as you pull the grinding tip out of the chamber, and dump it into a container. If you are looking to grind a large amount, this isn't the grinder you want (use a clean coffee grinder or a good blender). This is for daily use amounts at best. In fact it probably holds a little less than an average 2.1 inch manual grinder. That being said, this grinds more uniformly than the manual grinder and it's is easier on my arthritic hands to simply fill it and press a button than to use the manual grinder. I like it and I'm keeping it but I took off one star because the herb doesn't pour through the tip (even with tapping it against the bottom of the container) like it appears in the photo.

I spent nearly an hour online researching some of the best grinders and this is the one I went with. I had really high hopes based on all of the reviews but it was a complete failure. I will say the design of the product was really nice and heavy, but it just fell super short of doing what I needed it to do.First off, the fact it can't even handle 3grams at a time is really disappointing. When I have a bulk amount I want to grind up, this would take me all day! If you put too much in the chamber, it won't work (nice safety feature) but super annoying it could never handle what barely seemed like anything.Secondly, the tip of the chamber really had me thinking it could easily spit out the herb into where you want it to go. That is not the case. It's a huge hole as well, would have made sense if it was smaller and more precise.Lastly, nowhere to keep the crystals of the herb in this grinder. That is very important to most...chefs lol.The grinder does a terrible job grinding. I really wanted it to work, but even if I paid $10 I would return it. Save your money and buy a better grinder.

As a volcano owner, I was looking for the perfect grinder to really get that fine, fine grind that's ideal for that kind of vaporizer. While this grinder doesn't technically function the way it's supposed to, it works amazing. I typically like to load it up with a pretty sizable amount of flower after breaking it up a bit with my hands, and then I grind it until I don't hear the chopping anymore. If you use a lot of flower, continuously rotating the grinder up and down will keep the bud from compacting at the bottom under the blades. Here's where the issue is - if you try to get the flower out from the actual funnel piece, it rarely comes out. Maybe my flower is just sticky, but I personally like to grind it fully, unscrew it from the base, and just use the brush to collect all of it out from the bottom, larger end. Granted, the funnel will work if you use less material, this is just something that happens from loading it up too much. If you're careful, you can easily grind up to a gram at once, just have to be sure to not let it get stuck in the process. Overall, compared to literally any other grinder I've used, this one slaps them away. It's super easy to use, much quicker than a normal grinder, has much more variability in how much you can grind, keeps it charge for a really long time, includes the brush to get the material out, and always gives a really nice, fine grind. There might be a bit of a learning curve, but it's pretty easy to get the hang of. I hope this review helped whoever needed it. Thanks!

Was a great grinder , as much as I wanna leave a 5 star review , this unit only lasted me a year & a half I believe as the battery just would give out after me having to shake the stick bcs of all the bud that would get caught up in it , unit was charged but didn’t wanna power on , I’m a heavy smoker . Unit only lasted year or so , good stuff for ur money .
