Octopus, Vulture, Taskmaster and more. Basically, they are always on me and I want to keep them charged whenever possible. Overall quality of these roof rack crossbars is pretty good. Its great for putting treats in too as the little holes allow him to play to get the treats out. Most of the features that are advertised work except the weather for me. The mic is a little shorter then I would like but its great other than that. I think my big toe in particular is just a bit longer than some but short of chopping it off I just have to cope. Mine came scratched up, to be expected from a return. I have finally found them. I am impressed.
