Ceramic burr destroyed itself
Color: Silver
For the first two-plus months it worked fine -- the perfect grind and the perfect amount with a full barrel for my oversized coffee mug.
I've been using it once daily, more or less, on a medium grind setting of 25, and this morning the ceramic burr started to eat itself. This is not acceptable.
Follow up:
Circle Joy contacted me and offered to give a full refund on this purchase, which was gratefully accepted. This is outstanding customer service.

Best price for better tasting coffee
Color: Silver
I am a coffee snob. I only get beans. I have been using a magic bullet blender to grind, which actually does extremely well, but the grind wasn't quite even enough. So I found the cheapest, ok quality grinder I could and bought this one. I absolutely love it. It take a while to grind, and it only does a little at once, but whatever. This thing works great and my grounds are now even. The burrs seem to be of decent quality and the whole device works smoothly.

Reliable favorite kitchen tool
Color: Blue
This wonderful tool may be the most used tool in our kitchen. The hardest thing about it is to remember you can push the button and it runs- you don't have to hold it!. The charge on the rechargable battery last a long time- about 1 recharge per month- and we use it daily. We use the mixer attachment most. It works great for protein powders, collagen, iced tea or lemonade mix. It cleans easily and is waterproof- just make sure the cover is over the charging port. We have used it to froth milk, whip eggs, and as I said we use it daily to mix beverages. I worried about the price, but it is a great value because we bought it in December 2024 and it is more powerful and has already lasted longer than two whimpy ones.

Quality
Color: Black
This is by far the best frother I've used. Battery life is great. Its UX is excellent. Feels nice in the hand and has great power. Also like the on/off button as opposed to haveing to hold a switch down. Looking forward to getting their s3 scale.

Overall good frother
Color: Black
Bought the Maestri and the Zulay frother to test which one is better since both had good reviews. Returned the Zulay (see Zulay review) and kept the Maestri. Been using it for a few days now and works well. Mixes chai and hot chocolate well. It has one speed that is a good speed to mix, but not so fast that it causes the drink to spill over the top as long as the cup is filled to about 80% full. Because I tend to use the tall 20 oz Contigo autoseal cups, it could benefit from offering longer attachments to reach the bottom of the cup (note: that I did not find any company that offers longer attachment arms).
