I very impressed with this toy... a lot of value for the money. I opened the box to review the assembly instructions before Christmas morning, and took advantage of that opportunity to affix the stickers. A little disappointed when I realized the operator figure is not included. We also found that our rechargeable batteries would not work, although non-rechargeables worked fine. (The positive terminal on the rechargeables we use is just a little - very, very little - shorter than on Duracells and Energizers, and just-a-little-too-think plastic tabs in the battery compartment prevented good contact. Go figure!) Otherwise, no problems. Wish the wired remote attached to the lower structure rather than to the control cab, or that the wire was longer, but it wasn't really a problem. We used fifty cents or so in pennies in a ziploc bag as the counterweight - worked great. I also trimmed just a little bit off the "hook" to make it easier for grandson to attach lifting loads. He loves it, and continues to play with it. It's a hoot to hear him grunting and groaning "trying" to lift a little cardboard box - which probably weighs less than an ounce: "Uh, uh, it's so heavy... need to use the crane." He also uses it to load his stuff animal friends from the PLAYMOBIL dump truck into a train, run them around the track a few times, and then off-load them back into the truck. This is a terrific toy, well worth the $25 I paid (with Prime shipping).
