Great for quick updo
If you have reasonably thick or long hair, have zero time/patience/skill and are looking for a quick way to look presentable for work, this comb/pin thing is great. I haven't tried all the styles pictured but I often wear a low &#34;knot&#34; style bun, and this thing keeps it in place as well or better than other methods I've tried (including using a a gazillion bobby pins, or a couple of  those &#34;corkscrew&#34; pins) and in less time. It takes a bit of judgement to wedge it in comfortably without the prongs pushing against your scalp. One star off because it's pretty large (the ends will show unless you have a LOT of hair) and because I've noticed the two central prongs do deform a bit with use. You can easily bend them back so that all 4 prongs are parallel again - but I suspect over time the metal will fatigue. But with two units in the pack, you have a backup if one breaks.
