If you need the structure, then you'd probably get a lot out of it. However, imho, their strategies, especially on the logic games section, are needlessly complicated. You spend a great deal of time learning differences between the types of logic games, the potential set-up for these different types, etc... The problem is, you spend time learning all of that, instead of simply learning LSAT tendencies and strategies. You can spend hours analyzing differences between game types, or you can take the same time and realize that there is a finite list of question types, and they tend to be repeated over and over, despite the differences in game types. If you focus on learning the rules and making deductions based on the rules, then none of the other stuff really matters.
I've done thousands of game questions over the years as a private tutor, and rarely has it ever became an issue whether the game was a sequencing, or hybrid, or matching, or grouping, or whatever. The strategy remains the same, the question types are all similar, and the traps are certainly all the same. I'd focus on learning those things; tendencies, strategies, traps, and how to properly deduce facts from the rules, and you'll be fine.
Just my two cents.
While their materials provide mostly decent practice tests and questions, I've found, more often then not, their explanations to be inadequate, and in some cases, useless. Its all up to you and what you're comfortable with. I'd investigate local law schools and see if they have recommendations for private tutors. You can potentially save a lot of money and get a lot more out of it.
