The media could not be loaded. Β UPDATE: Notice to owners with ceasing, crashing units. This seems to works WITHOUT THE SCREWS super tight.. I put 2 silicone grommets(from small oil vape cart) on screws and loosely tightened them in to block holes and its WORKING AGAIN! LOL! Hooray!When it starts running clunky if I tap the base on something solid the gears align perfectly again and it runs smoothly but not for that long. I have to tap it again when the gear noises get louder. It does not get jammed anymore though which makes it much more useable. It was not useable in the original post production condition it was sent in, gears would jam.Complete failure of testing on this product this product. Not surprising I guess, in this case.. but I was super bummed at first when this technically broke. I paid $20 for this and unless they fix it thatβs probably a good price. I never dropped it or abused it. Use dryer, easily grindable product. You must break it up pretty small(half pea-size). Start grinding away from material and then shake them down onto blades or it will just jam up. Dense moist stickier stuff need to really be broken up but it will increase the flavor and enjoyment once you learn how to use it and empty the container. Load a small nugget big enough that it wonβt go through hole in glass bowls then load on top. The keif will stick to the sides but itβs just static and can be gently knocked out of container with a suitable tool. I use a typical rounded Rodgers pipe knife, gently scraping it downward and see no damage but the blade edge is pretty protected by all the sticky residue on it. Itβs not glass but very hard plastic. I donβt trust plastics either but itβs seems ok. I suppose you could make a plastic tool out of one of those lapel straighteners or something if youβre worried about scratching it but remember, you are just knocking it of not scraping it.I had to sharpen the blades with a fingernail file initially and it started working much better. Just follow the angle and drag against the cutting edge a few times you will see it start to appear sharp again with the right angle.Obviously it will grind better with a full battery too. The battery lasts a long time for me. Weeks or even a few months.I did the vid to show it could be easily modded to work if yours broke and you have some DIY skills too.Actually beside the major oversight with the motor gear connection this has turned out to be a pretty solid unit and I have used it a bunch now.I didnβt like all the powder coat on the cap and canister because I tap them together sometimes and noticed a couple chips so I used a dremel wire brush to clean it all off. It came of pretty easy and thereβs like no risk of any of that paint getting into product now.. Maybe the could leave the part raw metal next model

So this thing works good. I like it a lot. It is pretty quiet, good torque strength and grinds down very fine. The problem I have with it is that the herb tends to get stuck around the base and when you unscrew the tank if you are not careful you will lose it all. I tend to make sure I am over something when taking the tank off. Funnel shaped top works great for dispensing herb directly into other things. A bit pricey but worth it.

The only thing is the end result is inconsistent the bottom is very fine while the top is not but overall it is very powerful and durable and does the job well . Also I guess someone needed to try it out before mailing it cause the wrapper was off in side the box and it was used still had alittle shake in it .

Seems well build, rechargeable, easy to use, does the job well.The only negative I can see is that it is difficult to clean. Not a big deal if you are always grinding the same item.

This is a great for very dry stale weed. If the weed is still fresh then it wonβt grind much of it. Or you have to break the weed up with your had. First then put it in. Overall a great product for the money I spent. Itβs also make a perfect grind for rolling joints.

Feels like a quality product. Here’s the thing, i loaded an eyeballed amount of herbs in there and i tried to pulse it. don’t do that. things will get stuck. just run/grind till everything is shredded. For what’s in the market, I’m thrilled with this product at the price point i got it.

You have to load small amounts but it works okay. Would rather use other methods

I got this a month ago and it still works on the first charge by the manufacturer. Wow! I always struggled with manual grinder because it does take an effort. This little thing literally saves my wrists. You just put in small pieces in and I donβt even close the cap, I just top it with my finger and it eliminates the need to screw and unscrew the cap. The chamber itself is pretty roomy and can also work as a storage for leftovers. It turns off by itself and I have also read that the blades do not operate when the chamber is off the base. Nice! It feels pleasant to touch and operate. I also use a βpokerβ to push the product off chamber walls. Itβs sticky sometimes, if you know what I mean. Freezer helps (Just donβt put the battery in). Some reviews claim various issues, mine has none. Even if it dies, Iβm ready to buy another. I highly recommend this. I rarely write reviews, but this time I just had to. Many thanks to the manufacturer. Superb product.
