1. They do their job.
2. At this point; after a full winter and a half, they are still intact, but the velcro straps are starting to come a bit lose because of the stitching. They are still attached and work properly, but I have to be delicate with them.
3. Unless it is extremely cold I wear them without the Inner fleece liner.
Honestly for the 50% I would say it is worth the buy, just don't expect anything extraordinary.
