I donated to this Kickstarter and ordered myself one because I think its a really great tool and stands out from the rest for a number of reasons.
- It serves as both a steadicam and mini tripod
- It unscrews giving you the ability to attach your mobile phone to a standard tripod
- It has a flexible build and will fit any phone
For me number 3 is a big deal because most tripod mounts out there are normally made specifically for the iPhone and cant fit other phones, now you might wonder, why is that a problem for you since you have an iPhone, well the issue is Apple changes the body of their phone every few years and I am tired of buying new accessories for each phone. Also for $14 this thing is a great deal.
Check it out on Kickstarter, they have a lot of material explaining the build, how it can fit a variety of phones and all the other features.
