The cable used to interface with your rig is a little unique, in that it is a 2.5mm - 3.5mm and it is reversed with the tip being the dah. So it is a little different than the typical set up. If you are using the paddle with an FT-817 or a KX-3 or similar commercial transceiver, a simple adjustment in the menu will fix the reversed cable issue. If you are left handed, then it's perfect. The problem comes if you use the Pico paddle on a home-brew radio that doesn't have the ability to adjust the dits and dahs. You can do you own fix by cutting and reversing the wires and I suppose if you are using the paddle at a home station this would be sufficient, but the cable wires are thin and the solder job doesn't hold up well with portable use. There is a pre-made reverse wired cable available from MTechnologies that is a much better alternative.
One nice feature of the paddle is the quick mount. It a very strong magnet that allows you to mount the key on the radio. In the field this is a nice feature and prevents you from having to hold a small paddle and log at the same time. I recently used it in combination with my MTR on a SOTA trip and I really liked the way the radio and paddle were integrated.
