Siglent protects its scopes with a transparent screen protector sticker, and they manage to deliver their scopes with fans that produce almost no noise
Why can't Rigol adopt the same? How difficult can it be to leave the screen protector sticker on the LCD screen?
How difficult is it to source fans that are less noisy? Are none of the Rigol engineers using their own scopes for hobby projects at home? Or are all the Rigol engineers hard hearing?
Some distributors (without naming names 'hypen uk dot co..") provide the so called "quality inspection" service, where they open the box, test the unit, and provide a CD with the latest firmware and UK mains lead for the Rigol scope.
Honestly I don't see any value in it, apart from confusing the customer questioning if he really got a new unit or not.
1) Firmware updates everybody can do themselves
2) Spare UK mains lead has every self-respecting engineer lying around in his home
3) With the extra safety inspection the distributor questions the QA processes from his own supplier (what about trustworthy relationship between distributor and supplier?)
Just leave the carton box closed! Your extra service provides no value whatsoever.
