  • Last week I bought one of those giant vacuum insulated travel mugs (not a Stanley) from a discount variety store, along with a bunch of other things. After I paid, the cashier asked “do you want the receipt?”, I normally say no, but this time for some reason I said yes. After I left the store, my kids needed to use the restroom, so while they went I sat down on the bench and absently looked through the receipt in my hand. I immediately noticed I got charged twice for the mug. The cashier must’ve double scanned it. I went back to the store, showed a manager my receipt, and they refunded me the difference.

    That was technically my last refund, but the last product I actually returned was a set of tws (true-wireless-stereo) IEMs (fancy earbuds). They were a brand new model just released with great reviews, I bought them from Amazon, received them, and used them about a week. During that week I noticed every time they were in my ears, my ear canals got super irritated and my ears felt warm. And whenever I removed them the insides of my ears would be crazy itchy for hours afterwards. It got to a point after a week of use that my ear canals would swell and close up about 15 minutes after I put the earbuds in my ears. Didn’t take a rocket surgeon to work out I was allergic to whatever material that earphone was made of. I still had the box and all the packaging, submitted a return to Amazon with the comment “my ears are allergic to those earphones” and they accepted it no problems, I got a full refund.






  • That is not an air conditioner. An air conditioner needs a compressor, evaporator and condenser, this has none of them. What you have is a desktop evaporative cooler. Your theory of how it works is correct, the energy to evaporate the water is pulled from the air, that cools the air. But yes, the heat and moist air still stays in the room. Note, this only works in places with DRY air. If you are in a tropical location with humidity, this will not work because the air is already close to saturation with water.

    There are large rooftop versions of this called swamp coolers, installed in places that have short hot dry summers, they work because the heat is still transported outside the building.
