These things are amazing, no more bobby pins. really easy to use and cheap. I have meduim length hair and these pins hold my bun in place, the only problem is that I have layers in my hair and the shorter parts of my hair fall out , but it is ok. I am not sure how these might work for very fine or very coarse hair. Overall, great product, I would definitely buy again. P.S: if your hair is really greasy, the pins won't stay in for long!!

These seemed brilliant and get so many good reviews - but they DO NOT work in my hair!! I have medium-long THICK hair, and these simply DO NOT hold my hair up. When I finally get them to twist all the way in, they become so lost in my bun that I cannot get them back out. I had to rip them from my hair. I've tried them multiple times and never have had success with them.

I love my spin pins!! They're perfect for creating any sort of bun or twisty updo -I can do a cool figure 8 thing with them if I want to be a bit dressier. I have relatively long (about 5 inches past collar bones), layered hair that is THICK and I can get it to stay up with just one of these. Two really anchors my hair down- I could exercise with them. If your hair is shoulder length or longer, don't hesitate to buy! If it's shorter than that, you could get one of the three-packs of smaller ones and make little buns.

I just bought this yesterday out of curiosity because half of me was really amazed at how it can replace around 10 hair pins at once and half of me wanted to try it out just for the heck of it. It was cute little twisted barre hair pin which you twist around your bun at the top and at the bottom to secure it and my oh my, to my surprise, it really does work!It held my bun into place no matter how thick my hair was and what was even better was that it eliminated the use of hair ties which completely didn't damage my hair (because no amount of hair pins would be able to lock in my thick hair in place so I'd use a hair tie or elasticband which in turn damaged my hair), totally buying more when I hit the drugstore.

I love this so much, I bought a set for my sister and a second set for myself. I have very very flat straight hair and I always have trouble keeping it up w/ bobby pins, but never again now that I have these magical pins. I also have the up-do pin, but my hair has trouble staying up with that so I use the spin pins with it for an all day/night simple up-do.

Def. love this. I have coarse and long hair and i can twirl my hair into a bun and place one spiral in and it holds for the whole day. Totally became a part of " beauty hair and accessory" bible. Love it, replaced my hair-ties :)

Easy to use.If you don't know how just you tube it and there are a bunch of how-to's ,which helped me tremendously. Love em and buy them every time I see them ;-)

I LOVE these pins! It's just kinda expensive, about 6-7 bucks for only 2 pins, as opposed to only 2-3 bucks for 300 bobby pins. But still, these 2 pins work wonders. You pretty much only need these two to hold up your hair. I wish they had invented this way earlier, it's my first time seeing anything like this (first found it summer 2011). If I lose a pin, I'm definitely going to buy a new one. It is somewhat worth the price, since I can't find anything else that can replace this.

I have been looking for a product like this for years! My hair: Long, waist length, layered, slippery and straight Asian hair. Not coarse, but I have a fair amount of it. It doesn't hold a curl. I've never really managed to hold a decent bun with bobby pins or even hair spray. I have bought other bun making products over the years to no avail. It took a couple of tries with these pins and still some layered ends would escape, but this tool gets me the closest to buns ever. They are comfortable and if done properly, last at least 3 hours.
When I went to buy this, there were only two dark ones left. You really can't see them in my hair, but if you have fine or fair hair, it will probably be visible. Wal-Mart $6.50+tax CAD. Going to stock up on these since I can see myself using these things for years. I will also try the mini spin pins which should give additional support.
Tips: Spin inward into the bun toward the scalp. I can actually feel it going through the bun and also catching the hair at the back; this gives it the secure hold. Twist your bun very tightly and tuck as many ends in as possible. I use an unwrapped hair elastic around the bun because my ends refuse to stay tucked.

First time I could do a classy bun (meaning one that doesn't look like it belongs to a mental patient/cat lady) on my very thick fine-textured curly hair. Two were enough but I think I'm gonna get a 2nd set for more style variety and in case I lose them. Price is a a bit steep at $6CAD for a set of 2 but they do the job.
