Ultimately, i think it's up to you.
in an ASUS forum, you're (probably!) more likely to get the advice to RMA and give the device another chance, and they wouldn't be wrong.
but if a full refund option is available...
getting your money back sounds like a much safer option, no?
then take your time to really carefully choose one laptop you'd really like, test the
out of it before buying (if at all possible).
i'd do this if i were you (imagine that i'm in your shoes, and talking to the shop boss):
"i have this money back, i'm willing to give the shop another chance, but only if you're willing to let me test-run another laptop on spot before putting my money down again"
"what dya say? sound like a fair deal?"
no siggy, saw stuff that made me sad.
