wa lau ... then RM400++ just gone like that ???? Can even open it manually and see how to re-insert another rechargeabe battery ????

I knew this mouse is big eater but never though is so bad design..... lucky i don't own this mouse..., even my G7 No any Lag , everyday use 7-8 hours, still can last up to nearly 3 months with a standard TESCO alkaline battery...

KOVA still ok to consider. But don't really agree with you to "think" about Rapoo.... Design looks OK, price cheap but.... realiability is a "big Crab"....

my friend like cheap coz its below Rm50, bought one, after click for few days, the click button went stuck sometimes, later cursor starts "unstable" or not responsive... after i help him "tear" out the mouse inside and check, found that it was all made by cheap IC.... poor soldering job....

In that case, it proved 2 things:

1. Mamba is a "Heavy Battery Eater" OR Using "not so" good wireless technology (co nowadays, good and decent wireless mouse are all "low power consumption" oriented ).

2. OR .... the worse is...... they bundle with lousy rechargeble battery.

My statement might not be "like" by someone.... but its a fact that i can think of.
