Query: Very Underwhelming

While these do heat up quickly they do not work very well. I have very thick long hair and wanted more large rollers. These rollers do not provide a decent curl. The clips did not work and I had to purchase 8 butterfly clips to hold the rollers in. I wouldn't recommend these rollers.I will go back to my cheap clairol "Set To Go" rollers that work beautiful, I'll just have to get another set as these only come with 5 large rollers.These were expensive and disappointing don't waste your money.
