I have one of these - a couple of observations -
1. The angle of view is pretty wide - when I try to not have myself in the image, I often end up with either my hand or foot in the frame somewhere. You can create some interesting vertical shots by pointing the camera at the earth and having it spin around so you have an image that is earth - sky - earth - rather than a horizontal pano.
2. In cold weather (less than 32F) the camera will not spin around. I think the rubber band drive belt shrinks enough that it's too tight and the drive mechanism can't overcome the resistance of the drive belt. I've looked around for a slightly larger o-ring but sizing a o-ring without a gauge is difficult as there are 1000's of o-ring sizes. I'm sure McMaster-Carr has a larger ring if I could just decide which one to order.
