This is a handy tool to have for repairing small dents, I tried it on a few bigger dents but it doesn't work on them. I should stress that it is extremely important follow the instructions for better results.
This requires patience and may need to be repeated several times to fully remove the dent.
There are several tabs for various uses depending on the shape of the dent. The only thing that I found frustrating is the 2 side arms that balance the bridge. They are not fixed and allow for some movement, under pressure this means loosening the tension and redoing after balancing.
This is not a major flaw and it does work great on small dents, well worth trying this before going to the body shop.
