Magnetic Quick Mount
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.

Another nice feature of the Pico is that the paddles retract into the housing when not in use. I'm always in search of an efficient, light portable solution for SOTA Operations. These set-up works very well.
I have no financial interest in this product, I'm just sharing my experience with it. If you Google it you will find the dealers who carry it.
