I received these in the March Beauty Box and I'm amazed at how good these actually are, they claim to be as strong as 20 normal bobby pins, which I think is true!
I have long fine hair with dry ends, which I put up in pony tails and plaits very often, I don't tend to pop it up in buns as much as I would like as I find bobby pins can't hold my hair up, it slowly falls out during work. (Cheerleading coach and Zumba fitness instructor)
I gave them a test at home first with two bobby spinners in, it gave me lovely hold, and a nice full bun, I was really impressed! Next I tried them at work, and WAHOO! It stayed in all day long, two cheerleading practices, and one hour of Zumba! They work a treat, they slide in easily, and are hidden underneath the bun.
I have found that the colour is starting to chip off them all though, I'm not sure if its because I've got them wet, or that is what happens after a while.
Also, I don't think they can multi task for anywhere as much as the regular bobby pins can, it didnt work for a quiff, as it stuck out too much, or a half up half down do. So thats a bit of a shame, but to know I have a perfect bun that will hold each time is great.
I should preface this review by saying that I have very thick, long hair. Usually that means 20+ regular bobby pins to achieve any sort of up-do, but after picking these spinners up from the vault my life has changed for the better! They look super complicated and a little dangerous, but for most situations I prefer them to regular bobby pins. I can keep my hair up in a bun with only one hair tie and one spinner, which means no hunting through my hair at the end of the night trying to find stray bobby pins to remove. For smaller sections I still use regular bobby pins, but only one or two. They also don't slip out of place once they're screwed in, and are surprisingly easy to use. I've never needed more than the three that come in a pack of these, and they're only a couple of dollars, so definitely worth a try in my opinion.
