The typical good/bad letter thing doesn't matter for names like these.
The good/bad letter guide is for acronym names (ie 2 or 3 letter) and the number of words associated with each letter.
This name would be more likely fall under a "brandable" name than an acronym. The concerns with brandable names is letters that sound similar to each (that could cause confusion) and how pronouncable the name is.
The itug sale is probably right on in terms of quality to reference.
