Good product works fine most CAD software. Very handy to use via Bluetooth.

Good product but not compatible with all CAD programs. Best used via Bluetooth than USB.

Very impressed with the quality but then all 3DConnexion products are very well built. Having the 3rd centre mouse button is brilliant and the software gives some really ability to customize the setup and how its used. Its size is not overly big so is a little smaller compared to say the Logitech MX. Would be happy to buy this again.
