Responsive mouse, good battery life
The Trust Ozaa feels great in the hand, and its clicks are very discreet (silent at a distance of just a few metres). Its responsiveness makes it ideal for office use (gaming use not tested). The battery life is comfortable, and the choice of a rechargeable battery is a plus compared with traditional batteries.
On the downside, it would be interesting to switch from Micro-USB to USB type C, and to integrate a slot in the mouse to store the wireless adapter, as it can quickly get lost when changing computers.
