Not for me,

Don't get this if you want a conventional language-learning course!
The concept seems to be that you learn vocabulary first, and then grammar is introduced to enable you to use that vocabulary to constuct meaningful sentences. That seems reasonable in theory, but in practice I found the "helpful" mnemonics for the vocabulary extremely irritating.
Finding a vivid picture to associate with a word or concept is a useful memory technique, but I think it only really works if you use your own images that are relevant and meaningful for you. This course uses standard images which are, frankly, often very odd.
As an example, the first word is "cat". We are told: "The Spanish for cat is "gato". Imagine a lovely cat eating a gateau." It only gets stranger from there. For a dog ("perro") we are to imagine a dog pirouetting. For a cow ("vaca"), we should picture a cow cleaning a field with a vacuum cleaner. I wish I was making this up.
If that sounds like it would work for you, then this might be the language course you've been looking for. I just found it annoying.
