Ninja Foodi Coffee & Spice Grinder, Compatible only with Ninja SS100, SS350, and SS400 series blenders, Compact, Pulverize Through Tough Spices, 12-Tbsp Capacity, Stainless Steel & Black, XSKGRINDER

Loud as all hell, but such is the way of Ninja products. It does a great job Blending and I love using it for coffee and herbs. Easy to use, a little awkward to clean but not too bad. If you'd prefer something quieter that does almost as good a job, getting a regular cheap coffee grinder would suffice. However, I like the deep capacity of this one and feeling fancy using my ninja blender. Glad I purchased!

Small but mighty! Our 16 year old Cuisinart coffee grinder finally died, so I was on the search for a new one. Didn’t want to spend a ton of money (especially given how many bad reviews every newer grinder seems to get these days), so after finding this attachment, I decided to give it a try. Soooo glad I found this thing! I love that I can just put it into my Ninja Base (I have the SS101: Ninja Foodi Smoothie Bowl Maker and Nutrient Extractor 1200WP 4 Auto-iQ) and press “start” and it does all the work for me. (My previous grinder required me to hold down a button the whole time). I tried it immediately, and found that it ground the beans pretty evenly, and washing the attachment/lid was quick and easy. While I wish I could grind more at a time, I don’t mind having to throw in an extra cup of beans in order to make up the difference. (Being hands-free makes all the difference!) If you have a Ninja base and you’re looking for a grinder, I definitely recommend this one! Just make sure your model is compatible first!

For starters, the listing doesn't say what it's supposed to attach to. But after buying and realizing it wasn't just able to run on its own, I was happy to find that it attached to the Ninja IQ blender we already had. But when I went to attach and check it out, it popped out of place, and my blender started to smell hot. So, I waited a couple days and debated on returning thinking maybe I'd try again, that I didn't do it right. I tried again, and this time I had it in there better but my blender started smoking. I shut off right away and couldn't get this thing returned fast enough! My blender is fine, I thankfully didn't ruin it because I use it all the time. I typically love all Ninja products, we have several, and will continue to stick with Ninja, but this one is a no go for us.

I've only used this grinder for spices, not coffee. Paired with the power of Ninja Foodie I think this is the best spice grinder I have ever used (I think I've had about 3 others). I can confirm that it does in fact work with the SS401 even though the model is not listed in the description. I set it on smoothy, or extract if you want it very fine, I think extract over does it. For example: I bought a package of Leggs Italian Sausage spice mix, and the the spice mix (as I expected) had whole fennel seeds mixed in, that's not for me and my sausage! So I plugged this grinder into my Foodie, set to smoothy, fine powered spices, problem solved!I did just out of curiosity try to do fresh garlic, I would not recommend it, it's clearly advertised as a spice/coffee grinder but I had to try it. I wish Ninja would make a smaller, lower profile cup for the Foodie, like this size to do veggies and spice pastes. I find the smoothy tall cup is too hard to scoop out spice pastes, and ends up just splattering everything along the wall of cup without thoroughly mixing, (knowing Ninja, its possible that they do make a smaller veg chopper for the Foodie, I'll have to check). And I LOVE my Foodie but that's for another review!

This blender jar may look small but it powders spices very well. The full lid doesn’t let the spicy powder to fly out. The process has to be repeated for larger quantities to be ground as the jar is small.

Great addition to my Ninja Blender. No need for me to have separate coffee grinder. Especially if you have a small kitchen, you look for ways to save space and get the most out of the appliances you have.

The first time I ordered, I received a used item. So I returned it and ordered a different one from a different online seller. This one was not used. But I found this grinder works well enough with the correct NInja blender base, which you have to research to find which Ninja blender base it can work on (they sometimes list it in the selling points). But it did not work that well to grind oatmeal into a fine flour. I got a pretty coarse flour using this grinder, so I put it though the Ninja Foodie blender itself after using the grinder, and the oat flour came out better. Now I just use the NInja Foodie to grind oatmeal into flour and it works better.

I recently got my hands on a Costco Ninja blender smoothie combination and was on the lookout for some cool accessories to make our blender even more versatile. That’s when I stumbled upon this awesome coffee grinder. I used to have a Braun coffee spice grinder, and it was a reliable tool, but it was a bit of a hassle to clean. Then, I found the XSKGrinder, and my morning coffee game has been totally leveled up! It’s super compact, easy to clean, and can grind your coffee in just 20 seconds on pulse. Plus, it’s a steal for the price. I highly recommend it!
