The innovation of the axle rethreader that fits into the normal skate tool looks good, but I could see people losing it or breaking the softer plastic skate tools if the thing just wouldn't go on, but also think how precise you need to be with the rethreader to make sure it goes on right could also leave a few people with issues if they don't use it correctly.
Any which way, it will be interesting to see them. Not so much that I would be trying to get hold of a set as soon as they come out though.
