What is something really stupid you purchased that turned out far better than expected?
I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn't work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I'd gladly replace if it broke.
I'm here in my van on a hot hot day doing 'work' (in this case a little browsing of lemmy).
cooling me down is a "arctic air' USB fan with a little water reservoir providing a misting action. I think I said, "as seen on tv" like six times after buying it because how stupid can you get -- but i needed a fan and this is what the local hardware store had that ran on USB.
Wow. I love it. Fast, quiet, low power, good air, and the misting function is awesome. I'd buy it again in a heartbeat. (assuming it doesn't break within a week).
