imo lame, just because no clicky sound then they call it  stealth, that means 7g / 6gv2/ normal logitech keyboard super stealth? noo clicky sound no lights, no bling. 

im using the same, DA black on goliathus speed...no problems here.
sure its not ur casing or something vibrating alot?

lansiao lah, no one likes ambi. egro ftw! SS got alot of ambi mices for you to choose, go get that brand instead.

i got both DA and Xai, size is actually pretty similar.
ppl think Xai is small cos its ambidextrous...but when compare both the DA and Xai butt is almost the same size...and not really that much smaller.

DA Length 127mm, Width 70mm, Height 44mm.
Xai Length 125.5mm, Width 68.3mm, Height 38.7mm.

DA height specs is taller, but when hold, cos it slopes away so much from before the center already, it feels smaller abit.
