You get what you pay for in this life.. the cheapest of either make is not
going to be the all time best ever mouse....
I'm trying to translate your comments into specific suggestions, and
to reconcile them with what I know about how computer products are
made.
In any line of high-tech electronic products, designing and producing
the custom-made electronics and software is a major part of the fixed
cost of production... often the largest part. The fewer different
parts you make, more you make of each one, the less each part costs,
and the less each product costs.
Thus, I would expect Logitech to put exactly the same electronics and
firmware in every optical cordless mouse it makes, so far as it
reasonably can. I don't know what exactly was wrong with mouse I had,
but it appeared to be a basic problem with the motion sensing hardware
or software -- something likely to be the same in every model.
As I recall, I paid about $40 (discounted) for this mouse. I could
have paid more if I wanted a rechargeable model or Bluetooth, but I
would not have expected to get more quality; just more features. I
would not think otherwise today unless I were given some reason to
believe that typical computer industry economics do not apply.
Maybe I just got a lemon, and if I buy another ten Logitech cordless
mice they will all work perfectly forever. But having had a bad
experience with one, I see no reason to believe that I will have a
better experience with another if only I pay more for it.
I'm really puzzled by your comment about battery life, because I never
mentioned that as an issue. I wonder whether you're confusing my
message with someone else's.
At this point I'm inclined to buy a Microsoft mouse next time, and
stay away from Logitech mice (at least cordless ones) for at least a
few years, until I can safely bet that whatever caused the problem is
no longer in use.
