- Relatively small, more the size of a notebook mouse. Not suitable for palm grip, fingertip going quite well, for they may Claw is a bit too narrow
- Rather light for a wireless mouse - which is good in itself, but is probably bought with thin material thickness. I own several Logitech mice which I use and have used, including recent models such as the 620 (or less a precursor of 705) or G9. None of mouse the mouse buttons one and two triggered as quickly. It's happened to me more likely that I have triggered accidentally right-click because the key has virtually no resistance. The finger must float quasi. I do not have huge hands, rather smaller, and with my mice such as the G9 is the finger gently to and can trigger a slight impulse to click.
- Radio contact is something ... mau. When I plug the receiver is about one meter between the mouse and receiver, separated by a centimeter pressboard. Already since the mouse has now and then dropouts. I use wireless mice when I only problematic can lay a cable or the way exceeds the usual ~ 2m cable. That I "extend" a de facto keyboard with USB hub need as Logitech recommends the receiver next to the mouse is certainly not a big problem - leads for me but the sense of a wireless mouse, including disadvantages like heavier, dead battery in unpasendsten moment etc - absurdity.
The mouse is not very expensive and that is why the comparison with the G9 is a bit unfair, but the sensor in the 705 absolute average and the mouse itself is five mouse buttons also. Except for the mouse wheel, which seems also optimizes material poorer over the years, it has nothing which does not possess a ten Euro mouse. The "feature" radio is therefore the big selling point - and since it is, for me, is insufficient.
Conclusion: no really bad mouse, but a mouse with limitations - and this is the price of a brand product is not appropriate.
