Pros:
I would put my level of experience above 'Keen Amateur', but I am not, technically, a professional violinist, so I can't say that I am.
The resin is OK. It's easy to handle, and provides a smooth, even coating on the bow hairs.
Cons:
I really don't like the cheap, cardboard box. Even just a stiffer cardboard box would be preferable.
It's not quite 'grippy' enough for my tastes. It seems to provide too smooth a coating. Even so, it's OK. Just, not brilliant.
