PRO:
- Big hand width
- Reliable sensor to date on all (non-glass) surfaces
- Gumming quite handy
- Touch panel not a novelty more but anno 2014 barely used since my Genius Traveller 355 already long in mice
- Unifying stations very handy
NEUTRAL:
- Mouse just too shallow
- Key drop to flat
- Ergonomics only sufficient with heavy use
- Build quality is just downhill at Logitech
CONTRA:
- Somehow too flat to ergonomically / points to fatigue
- Middle mouse button on the panel not be freely assigned as in older models
- Farbabreibung on the outer edge of the rubber coating (white instead of purple, looks like abrasion due to transport movements)
- Clearly too expensive for the performance offered
Unfortunately, no worthy successor to my tiny "Genius Traveller 355 Laser 'but just slightly larger for manual
with the same features at a price overpriced.
CONCLUSION:
The next move will be a convex Genius again. Really "ergonomics": As you know the word.
