Its ergonomics are perfect both in the handling of the 4 keys in its grip. The dongle plugs into any USB port without obstructing other USB ports due to its small size. It even has a diode to ensure good communication with the remote control when you press one of the buttons - its storage is done in the remote control to not lose.
The laser pointer is powerful, with good intensity and especially the red dot generated and good size (not too thin or too fat). Would recommend especially that the two batteries are of conventional size (identical to lounges remotes).
This product accompanies me throughout my travels and for all my actions.
