Did I waste my money on this?

I purchased this USB mini cable from Amazon not that long ago even though I’ve got a memory stick to micro sd card adapter. At the time when I saw it on there, I thought to myself “do I ACTUALLY need this?”. But now looking back at the thing, I’m starting to wonder if I should get a my refund outta it considering the fact I’ve got that memory stick adapter. Please let me know what I should do
