Bests & Worsts Reviews from Amazon

I'm sad to say these rollers are about to be headed back to amazon. Let me start by saying my hair is naturally wavy and typically holds a curl for literally days. Especially when I've used hot rollers in the past. When my old-style/old school rollers died (not longer heated up when plugged in) I thought these would be the closest thing - I can't find the old style anymore, anywhere. Conair is a reliable company, but I've used these three times now, without success. First time, I thought, well...maybe my hair wasn't all the way dry, so that's why it didn't hold the curl. Second time, my hair for sure was dry, and I used "hold the curl" hair product before curling, and hairspray after taking out the rollers...flat within the hour. Third time...maybe it's because my hair could've used a wash. Result: flat and FRIZZY! Also, I was not expecting spiral curls. I purposely bought these because they should be producing looser/beachy waves due to the size of the barrel(s). So it wasn't like I was thinking I'd get Shirley Temple springs on my head and then got loose curls. I got nothing. I even questioned my health...like, am I getting sick? Is my hair totally fried? It's not. I'm good. I'm super confused, because as I mentioned, my hair holds a curl in any weather, and can easily be refreshed for a few days after the initial curling (out late drinking, sleeping on it, ponytail, etc. you name it, my hair rocks). I'm super bummed out. Rollers were my lazy morning go-to. Now I'm stuck with the messy bun until I can find a replacement that works. I guess I should mention that they DO heat up quickly, and they are hot. So, it may be that my hair just doesn't like them. Or maybe it's too long. I dunno?
