Scale: This toy is modeled on large construction vehicles that turn into individual robots or one giant robot. It should be bigger than automobile-robots of a similar scale, and it is! For collectors seeking a giant robot that is comparatively huge, this is a monster! (The top of the head is over 15 inches). It towers over comparable toys and really stands out in a collection.Complex: This is not a toy for small children. Even long-time fans of robots that convert into vehicles will have a hard time with this item, even though the direction booklets are included and they are generally pretty clear. Changing each vehicle to a robot is a time-consuming challenge, but the reward is so worth it!Detail: These characters look really good. Toys based on cartoons like these may never have looked so good! The construction vehicles have nifty proportions and are posable. The robot forms are likewise very posable, detailed, and authentically look cool - action figures! Some of the parts are made of translucent orange plastic, meaning backlighting can make the eyes seem to glow! The giant robot form has very well-articulated hands and there is an LED inside the head that lets the eyes glow red! Everyone in our home who saw the glowing eyes was thrilled.Fragile??? There are many very small tabs and fittings on these guys. After turning the toys from construction equipment, to robots, and back, and then into the giant robot, nothing broke. Phew! There were several movements that seemed to stress key joints some movements in the process really created fear that the plastic would break. Since most collectors will just have the giant robot on display, it should last a long time (and it is more stable and posable than many similar toys) - but this set has such impressive sculpting that it really seems a shame to leave some of the other forms neglected.Summary - Not just satisfied, but thrilled and amazed. This is a really complicated and potentially fragile model/toy, but it really dazzles and the price was far better than anything from comparable toy makers.
