I've only used two of the adventures so far and they alone have been worth the price.
My campaign started recently and I needed a solid base to get into the swing of things. This product made it super easy and pretty stress-free, allowing me to spend a lot of pre-first-session time with the players to hone their characters.
The adventures are easily scalable, well paced, and wholly adaptable. I've slotted the two I used with minmial fuss into my overall campaign idea and plan to use the rest in coming sessions.
