Polaroid XS100I Wi-Fi action camera review:
The Polaroid XS100i is more or less a commodity action cam. By that I mean that it's a fairly generic camera that's been branded with the Polaroid name and doesn't compete with the bigger names in the category.
The Polaroid XS100i is an overall solid package for the money including built-in Wi-Fi and bike and helmet mounts as well as several other accessories. It has a standard tripod mount and is compact, lightweight, and waterproof without a housing.
The battery is built in, so you can't swap it out when the battery runs out of juice. Curved lens makes underwater video soft. Any camera shake causes Jell-O effect. Two apps are required to use all wireless features and there's some delay with live...
As long as you respect its limitations and keep the camera steady, the Polaroid XS100i is a good easy-to-use budget-friendly option for dabbling in hands-free video.
