I have returned two keyboards ,and I'll bet that the next purchaser never knew that they were not factory sealed. I repacked it all just like new, even putting the manual back in the plastic sleeve and neatly winding up the power cord. But the clerk never even opened the box to check it out, I could have been returning a box full of anything! Without a return policy I would not consider buying new, because the financial risk is too great. So I really value the in-home trial and I do not abuse it, but I am sure that abuse is all too common.
