I've tried several, and the one that stayed up the best and didn't break from being taken up and down was this one from walmart. https://www.walmart.com/ip/Mainstays-Adjustable-Tension-Window-Curtain-Rod-1-Diameter-48-84-White/14658166116 I got one from Amazon a while back that stayed up great, but when I took it down to change the curtain the tension spring wouldn't hold the second time I tried to put it up.
