Stance, by Kenu, is a $24.95 compact tripod for iPhones that attaches via Lightning connector.
The manufacturer says the patent-pending mounting attachment is made out of Grilamid®, a “highly durable and resilient resin.”
The connector is a ball-and-socket, so you can rotate it freely and even use it in landscape mode.
One last thing: Notice the integrated bottle opener on one of the legs? That pushed it over the top and earned it a spot on my keychain.
