Best grinders I have ever used
Color: Stainless Steel
I bought these 6 months ago and they are great. They have stopped charging several times. The problem is the salt gets on the contacts and oxidized the contacts and the unit stops charging. You take sand paper and clean the contacts and they work fine again. I feel if the material on the charging port is made with stainless steel and the contacts on the grinders themselves are larger, I would have given this a 5 star. Even As it stands, I would purchase these again. I have several bad experiences buying manual grinders that last about a month and break. These are High Quality, but need to upgrade the contacts.

Salt n peppa
Color: Stainless Steel
Not sure why I waited so long to purchase these! They are great, nice sleek design and they make cooking so much easier! They work so well and I literally just hold it over whatever I’m cooking, press a button and fresh pepper and salt are grinding right before my eyes! In the past my shakers have left salt or pepper on the counter but so far these have not, which is a bonus for sure!

Convenient and sleek
Color: Stainless Steel
These are very easy to use with one-hand operation. The adjustable grind settings work well, and the light feature is actually helpful when cooking. The stainless steel design looks modern on the counter. Grinding power is consistent and strong enough for everyday kitchen use. Pros: • Easy to operate • Adjustable grind size • Attractive design Cons: • Requires batteries • Slightly taller than manual grinders A convenient upgrade from manual mills.

Quiet, Powerful, and Reliable — The Best Grinder Set We’ve Owned
Material Type: Updated-Stainless Steel
After going through several cheaper grinder sets that never held a charge, struggled to grind properly, and eventually broke, I decided to invest in a higher-quality set. This one seemed to check all the boxes — sleek design, convenient charging stand, and an overall premium look — so we decided to give it a try. From the moment we charged them up, filled them with our favorite salt and pepper, and started using them, the difference was night and day. The grind adjustment is impressively versatile, ranging from coarse to very fine, and it’s much easier to adjust than on our old grinders. The charging base uses a USB-C connection, which is a big plus — it works with the same chargers we use for our phones. Aside from the initial charge, we’ve only had to recharge them once in more than six weeks of regular use. The grind quality is excellent, the operation is smooth and quiet, and they don’t sound like they’re straining like our previous sets did. If you’ve been disappointed by cheap electric grinders in the past, do yourself a favor and upgrade to this set. It looks great, performs flawlessly, and is absolutely worth the investment.
