Spacenight Electric Herb Grinder COMPACT for Flower Buds, USB-Rechargeable, 2pcs 1.7oz Glass Herb Chamber - Ideal for Everyday Carry

Excellent product. I use it for flower. I have had 0 issues. As far battery life. I bought mine a month ago and use it 1-2 times as week and still haven’t had to charge it once not even initially.

This little grinder works like a charm but has a couple of requirements that aren't in the description. First, you have to make certain that the small cup is Securely attached to the grinder. So, twist it on tight. Second, when you clean the blades with the brush, make sure you get the space behind the blades clear. It is hard to see how much kief is caught behind the blades so run the brush all the way around. After I figured out that the grinder won't work unless the blades are clean underneath and the cup is tight, I have had no problems getting the perfect grind for my pipe! After using a manual grinder before trying this one, I am a fan because it is faster and the grind is more even.

I love these little grinders. They are small yet powerful. The battery lasts for what seems like forever with a standard use. I love that it comes with the extra jar and have purchased several of these actually. They make great gifts. Inexpensive. Can grind down as far as a powder if needed. Easy to clean. Easy to use. Great gift idea.

This would be a great grinder, but..... #1. If the top isn't on there so tightly that you need pliers to remove it then it won't even turn on. When it does turn on it works great, but it's a struggle to get it get started each time. The top gets clogged easily & it's hard to get the product out of the top around the blades once it gets stuck up there. It's a good grinder for the money tho. Design could have been better but it works I guess. The top is much bigger than the actual part that holds the product & I feel like that's backwards. The design should have been even or flipped so that it hold more product & has a smaller top. I guess the design is done on purpose but I would have done it differently if it were me. Looks odd but I guess it's okay for the price. That's why I still gave 4 stars 🌟

Absolutely horrible. It grinds, yeah, but it cakes everything you grind into the bottom of the jar, and it can't be used, so you lose the product that you grind. Used it twice and had the same outcome each time. No way to see to contact the seller, so no choice but to return. What I'm grinding is too expensive to lose to poor design that cakes your grind.

Works perfect everytime. Grinds quick easy to use and a perfect size for an 1/8th. Well designed button functional device.

Hell ya, this grinder is the booooomb!!! Typical grinders have 3 compartments that are supposed to be cool and give you a different texture and consistency, but dammit this one jar method is clean, not as clogging/sticky, minimalistic, and hella time saving. It's not heavy and fits in your palm nicely. Even fully charged, it didn't get too loud, and it gets extra praise from me for having a shut off feature which times your grind and prevents burn out.

Shape is good.And it works well. ..

Quit working after few uses
