This is seriously the best fan. I have been forced into menopause thanks to breast cancer... and let me tell you, a fan is a MUST. Hot flashes are just not right, man. You need a fan to defeat the heat as soon as you feel it coming on. I have had mine since 2018, got it on Amazon. Somehow, the wires got damaged and it only works in a certain position now. I think I dropped it one too many times...oops! Batteries are incredible and the fan seems to last forever. I only use it for flashes so it is on for 3 minutes or so at a time. I bought this same fan for two other friends going through the change and they absolutely love them. I go everywhere with it too. My fan has been to Thailand, Malaysia, Laos, Canada and the US. It's a tiny bit bulky but it fits in my smallest purse just fine. Truly a life saver (feels that way, in my mind)! Ordering a new one now. Thanks Opolar! Excellent product.
