There are various (very pricey) commercial response boxes or pads (perhaps most notably Cedrus) that purportedly offer higher precision than regular keyboards. (Note that my question focuses on precision, not on accuracy, though similar doubt applies to the latter too.) However, I cannot find any study (peer-reviewed or not) that verifies this. Instead, I find studies that show that regular keyboards are very precise anyway (e.g. this, showing max 3-4 ms standard deviation). Is there any evidence out there for better precision with commercial hardware, or anything else that justifies their insane prices?In any case, is there any actual evidence out there for better precision with dedicated commercial hardware?

Are dedicated response boxes really better in precision than regular keyboards?
