I bought a smart watch. It has a SIM slot to make calls! It has a video recorder, Still camera and sound recorder. and an mp3 player. The loudspeaker is not up to much but for catching the moment it is superb. Always to hand (if you see what I mean).

At the price of 8/9 cups of coffee it is cheap insurance on getting the sounds. Battery needs topping up daily for surety, but it lasts about 3 days.

Quality? you get what you pay for. I filmed Auvergne burees (in the Auvergne) at a workshop when the leader was requesting no video (it is for private use anyway - good enough to see the moves).

I have bought about 3 wrist recorders that are extremely convenient and did catch moments but they are prone to go wally and the batteries need topping-up because the OS is in RAM. Even so, they become unusable eventually, possibly because of static electricity. Discrete but no loudspeaker. Pen recorder uses the same chip, architecture and software.
