No problems here... Great battery life and functions.
Color: Upgrade Silver, Size: Rechargeable
These things hold a charge forever.. I maybe charge them once every 3 or 4 months and use them daily. Good adjustment for coarse or fine grind. I would recommend.

Great grinders, bad recharging stand
Color: Upgrade Silver, Size: Rechargeable
The grinders work amazing and I loved them, but the stand that recharges them stoped working a little after a year.

Mediocre salt and pepper grinders
Color: Upgrade Silver, Size: Rechargeable
Pros: They do work, and they are rechargeable.
Cons: the motors run really slow, capacity is low, The charging tray you have to empty frequentlyto reduce buildup underneath the salt and pepper grinders.
