1st- I recommend using a brick separator to apply all stickers to this & all sets (except big nameplate stickers). Makes them easier to apply them with greater accuracy. This set doesn't have too many stickers but enough. All are easy to apply with a separator & I think they make the set look much better. Love the Richter scale! Overall great set. I didn't think I was going to like the volcano itself, but it turned out to be one of the better parts to put together. Way more into it than I though. It has a nifty lever to make the volcano 'explode' the lava rocks. However I think it could have been even better if it had one base plate & no big molded pieces ( we want to 'build the whole volcano', not build the base). Each corner of mine is slightly concave due to the big molded pieces, seems to be warping small base plates. My volcano kind of rocks back & forth because of this... The command center & truck are nice as well. Command center has a neat technique for hinges. Truck has a movable crane arm to pick up lava rocks. The crawler/ excavator is my favorite part. I really like the tracked vehicles ( the volcano crawler set #60122 is way better & recommended. As well as arctic base- 'retired'. Both have better tracks than this) this crawler has a better more complex rock breaker than 60122 & a different way to get tracks to move... not as smooth. The little cart with tipping bucket is unique & a nice addition to the set. The drone is nice but needs something to hold it in the air, maybe like clear piece that holds scarlet witch in 1st hulk buster. The minifigs are well done, includes 6- with 2 females, multiple different tops, & good selection of accessories. A couple green pieces were faded a bit & did not quite match the rest.. Great set with great playability. Definitely recommended for kids & adults.
