Packt are often denigrated as producing low quality materials here and in similar places. This is not an accurate summary though. Their business model as far as content is concerned is to be the first out with materials to help developers in leading edge software technologies. In order to do this, they push through large numbers of books and training courses quickly, many of which are from new or relatively inexperienced authors. Some of those books are the ones that cause the perception. They do, however, also have some very good books and training that can sit alongside of the big names and which are well-worth obtaining access to. There are places where you can see the popularity of their materials before buying which should help with content filtering. Like all of the other technical publishers, they have agreements with big organisations, who provide access to their library of content through their own subscriptions. Such organisations are, in my opinion, the best route into their training, as for many others. As an example, I personally have a subscription to the ACM. This gives me, in addition to its other benefits, access to several training portals including O'Reilly, who include all of the Packt content within their portal. The cost of this subscription is lower than any annual training site subscription, even the normal Packt one.
