Its not a common problem according to Devour as quoted below.
Perhaps, is the problem for the grey imported set or isolated issues.

common problem ? i never heard this.. so far from what i see from my customer, the unit keyboard built good , wifi as good as other ( so far only u310 , or u410 have wifi module problem ) and perhaps , only the touch pad a little bit drifting ( like inconsistent) ,but after adjust setting on synaptic , working well

User also no problem with it as quoted below:
