I've recently noticed that the wireless model wasn't available anymore, though. Well, it turns out that there's a successor: Perimice-720
Perixx sells it through their official US eBay account, currently for $40.
- Wireless 2.4 GHz and Bluetooth (still 2×AAA batteries; on/off switch)
- (6 buttons including 4-direction wheel)
- (dimensions 139×102×50 mm; weight 140 g)
- Three Adjustable Angles (plastic bases for 10° or 20° tilt)
- 600/1600 Adjustable DPI Level
- (1000Hz polling rate)
- System Requirements: Windows 7, 8, 10
According to the FCC submission, there will be a wired model too (Perimice-520).
