I discovered this little gem the other day and will be trying it out on my San Francisco outing soon. The remote is Bluetooth wireless and I will be testing how far away it will work.
I like the fact that it is compact and light weight while being machined from aluminum for durability.
This way instead of designing a 10 foot selfie stick I can take pictures from that distance with this remote. I love the way I look from 10 or 20 feet away.
