- It is heavier (two battery sticks "classic" while the VX Nano uses any small stick batteries)
- The sensor gets dirty quickly (Unlike the VX Nano, the on / off now covers the sensor in the off position, so this is a moving part that may very easily become clogged - especially if like me you have a cat ... 1 single hair stuck and the cursor stops responding!)
- After two years of intensive use, my left click is already HS !!! I used my VX Nano for about 5 years to deal with them !!!
I am extremely disappointed in the overall quality of this mouse, especially since I was a loyal customer of Logitech. Yes, I was, because I can not explain this setback other than commercial ends. But it will now be without me.
Note: For info, micro-switches of the VX Nano can be purchased easily online, if you are DIY, no hesitation (and this will be an opportunity to change the pads with Teflon models, which are also available).
