CDRKing ET-688 voice recorder

I overreacted because there was no charger with the device:
You are warned NOT to fall for this device!
The size has both advantages and disadvantages: Easy to carry on you pocket but is damn easy to lose or misplace!

The most important things are left off as optional devices, but I don't know if they are available. I need to come back Thursday. This for a price of 1780 pesos.

Mar 30. The device can be recharged using the supplied usb cable. Sorry for the noise. I now change the NOT to buy recommendation to BUY.However if the battery does run down and cannot be recharged anymore, you are out of luck.

There is a cheaper model for around 1,600 pesos with separate AAA batteries. Buy this one if you are a pessimist.
