I didn't learn a huge amount, but then given I picked it because it was within my comfort level, that's hardly surprising.
There are definitely a few down sides with this style of presentation. It's had to go at anything other than the pace the videos are delivered at - well that's not true - you can go slower by pausing them, but it's hard to skip ahead as you don't know what you might be missing. This isn't like skim reading hard copy where you can skip ahead and suddenly see something you think is important.
Still - for the price - it is excellent value for money! :)
