Perfect product, easy to put in, comes out easy and holds a style like 200 bobbi pins. I only have one gripe! It's my fault though, the darn things roll off fo fflat surfaces and I LIKE WATCHING THEM GO!!!!!!!!
Haha, no lips off for that.. I wonder if we could race them!!!!

love this! i'm not very good with doing things to my hair... even simple things such as putting it up in a bun.
my hair is super long (comes down to the small of my back), and putting it up in a bun with bobby pins just requires too much time and effort.

but spin pins, makes it possible in less than a minute! love this.
wore it to work, and it was held up perfectly. didn't become loose throughout the day.
i even work out with it up with spin pins, and it holds up great!

would recommend this to anyone!

I have thick hair that goes about halfway down my back. I recently got a perm and needed to put my hair back, but didn't want a line from a elastic. I use both pins as the directions say and its perfect! My front layers are too short to be in the bun, but I have colored headbands that I use and it helps my hairstyle look less "school-marm-ish." They are expensive, but worth the investment, IMO.

I bought these today and found they worked pretty well with my med-thick hair. While it takes a bit or trial and error as well as practice to get what you want, I find it a lot better than pins. I probably need 3-4 rather than the 2, but over all I would buy again.

These are awful! I purchased them because i often wear my hair in a bun, but these wouldn't hold my hair back at
all! I have fine wavy shoulder length hair, nothing too intense, so I was pretty disappointed these didn't work :/ you're better off buying bobby pins.

-edit-
Okay..I gave these another shot. I don't know what's different now, but they suddenly work pretty well for me. My hair is still around shoulder length and has gotten thicker due to not dying it or heat styling it. These used to literally just slide through my hair and kind of hang in this weird bun-limbo, but now they secure it and hold the bun pretty well. I don't use a rubber band or any additional pins. I'm really glad these work for me because I don't like using rubber bands for a bun, even metal-less rubber bands, because I feel like they damage my hair in the long run. Anyway, I definitely recommend these, but I think they work better for slightly longer and thicker hair so they have something to grab on to. When my hair was finer and shorter they just didn't work at all.

I got these after searching high and low at Targets and CVS stores. I know the claim is that they do the work of 20 bobby pins - and much like other reviewers, I don't agree with that claim.

I would say these do the job of more like 7-10 bobby pins.

I keep these in my purse in case my hair gets away from me. They are nice to keep around, but I don't think they are worth the hype they are getting.

The price was $6 or so for two spin pins.

I have fine, long hair. These are great but not absolutely fantastic for me. Maybe my technique is off but I have had hair fall out of my bun with these, and this has happened more than once. I do find that they hold better for me if I use an elastic to secure a pony first. When shaping the bun, you have to really tuck the ends in properly before pinning. Contrary to the instructions, I have great results when the two spin pins connect to each other. My best results are achieved when I tease/backcomb my pony before shaping into the bun, and then making sure I pin really close to my scalp. I agree with one of the previous reviewers who mentioned issues with the pins being a little long. Having said all this, I don't regret buying them and they are really easy and fun to use. :-)

I LOVE THIS PIN! I have very thick and wavy hair and these little pins kept it in a bun all day! This is a great little gadget to keep in your purse for last minute hair changes. It is quick and easy. LOVE LOVE LOVE

Holy Smokes what a GREAT invention. My hair is shoulder length and fine. It usually takes at least 4 bobby pins to pin my hair but I can use ONE Spin Pin. I have rarely been so impressed with a hair invention. LOVE This - give it as a gift ot stocking stuffer ! It stays in place all day. I only wish I had patented it first !

Love, love, love this product!!! I have thick, wavy hair that hangs past my shoulders and two of these pins hold it in place all day long! I work in a conservative office in Florida and often wear my hair up for convenience and comfort. I can let my hair air dry in the mornings and twist it up using these pins and it looks neat and there isn't a tacky plastic clip sticking out of the back of my head. I purchsed the blonde pins for $5.99 at Target . I would recommend these for anybody to use.....it's basically foolproof and the box has extra styling instructions! Great for hot and humid days when you don't want to take the time to style your hair but want to look polished! Buy it!
