The recent Apple announcement of selling a "smart watch" had me do some research and I discovered there are already a few others out there.
Last night Amazon delivered my Samsung Gear 2 Neo watch. After wearing it all morning long I've decided it's indispensable. It's a great watch. It does tons of stuff I don't need, but I love the notifications. I had to turn it off for emails because my emails are constant, but for text messages it's great - no more digging out the cell phone to read a text message.
It's really easy to use too.
