I bought one of these many years ago. Extremely unreliable and inflexible. Worse than even the springy Rat Shack ones. I really wish someone would put together a decent kit and guide these days. I did consider designing and marketing something myself for a couple of years but I never got past the conceptual stage. It wasn't going to be a "here's a load of instructions to follow" but experiments that lead to "why" through instruction rather than just mechanical reproduction of circuits verbatim. Even all the Make stuff is pretty lame shiny marketing crap with few explanations and intuition being developed. I have spoken to a lot of people who bought a load of stuff and learned how to plug things into things and copy and paste code. When it comes to "I want to solve problem X" there are too many gaps which leads to demotivation and large lots of arduino crap being sold in bulk on eBay.
