They grind well, but have design flaws
Color: Black, Color: Black
These worked great for a few months, but then minor inconveniences became bigger issues. While I initially liked these a lot...I would not purchase units with this design again Pros: These do grind well and have good adjustments to grind size. The battery lasts plenty of time for a long cooking session Flaws: -because the grind comes out the bottom the base fills up with bits and grinding dust very quickly -the location of the button inevitably leads you to pushing the button unintentionally when returning to the base -the charging contacts are very small which means the smallest amount of material in the base makes the grinder sit crooked...and not charge -in the past few weeks one of the seals on the bottom no longer will sit flush in the unit...which if course makes it sit crooked in the base and you guessed it...it won't charge. It seems to get a little worse as it is used more and I am waiting for it to basically become so bad it won't work at all anymore The amount of material in the base in the photo is from probably 3-5 days of daily use.

Good quality, easy to use
Color: 2-Speed Rechargeable Set with Base
I absolutely love these grinders. I always thought electric grinders were silly but I’m so glad I bought these. They work great. I like the adjustable grind and the light really helps. They look nice and are well made.

Best electric pepper and salt grinder for a very reasonable price!I
Color: 2-Speed Rechargeable Set with Base
I've spent over $200 on salt and pepper grinders including very pricey manual ones and a name brand electric grinder which was costly and had a weak motor. I bought these expensive grinders thinking I would get a quality product by spending more money. Well, it was a waste so I decided to try this highly rated Circle Joy grinder and, so far, it works incredibly well! The high/low speed works exactly as expected and at high speed, it grinds really fast. The motor is powerful and does not feel like it's going to give up even when grinding salt or pepper at high speed and on the fine setting. It is easy to refill, holds a long charge and just simply works. Buy this. You will not be disappointed... and say goodbye to having to wash your hands everytime you flip a raw piece of meat or chicken to salt and pepper when using a two hand manual grinder.
