Knob doesn't last
I first bought this mouse and was delighted with it, but after only a few weeks the scroll wheel was showing signs of fatigue and the up/down scroll was no longer working properly.
LDLC replaced the mouse with the same model, but unfortunately after a few weeks with the new mouse... same thing again, the up/down scroll was dead again. On searching, it appears that this is a defect in this series. So I wouldn't recommend buying it, which is a shame because apart from the scroll wheel, everything else works perfectly and the mouse ergonomics are optimal.
Thanks to LDLC for the quick replacement, top service as usual!
