"Well paced and genuinely informative. I like that you explain why a thing works, not just how to type it."
"The pacing, the density, the little jokes hiding in the code samples. Worth every cent and then some."
"Each lesson rolls straight into the next. The videos are not the usual sleepy screencasts."
