Overall, I am disappointed with this mouse for several reasons.  The first reason is that it simply does not hold a charge.  I place it on the charging unit each night and it charges overnight but usually by the end of the next work day the red light is already blinking, signaling it is almost out of charge.  I change the rechargeable batteries I have in this mouse at least once per week too and this is much more often than I have to change the batteries in my mouse at home, which is a different Logitech model.  As for the second reason I am disappointed with this mouse, I am frustrated by the fact that it looses its wireless connection to its base and my computer very frequently.  I will have worked all morning and then walk away for a few minutes to get a cup of coffee or what-not, but by the time I return to my desk, I will have lost my connection.  It is a bother to me because I usually have to try re-connecting several times before it takes.  I have only given this mouse two stars for below average.
