We have four Bruder construction toys so this review is going to show up in all four places. These are all very well made, lots of details. They are made of plastic and of course could be broken but they were thoughtfully designed and are reasonably durable. The mirrors on the Mack dump truck are probably the weakest item, but if they were to break off the truck would be otherwise functional. Toys break. We took this as an opportunity to try to help our three year old grandson understand that a little care was required if he wanted these to last and he's responded well. So far, nothing's broken on any of them, despite hours of use.These all have so much intriguing detail that the kids are immediately drawn to them. We have about a hundred buckeye nuts for them to push around and load without making a difficult mess. They all have moving parts that allow them to perform their real world functions. There are detents built in to hold position, so for example with the bulldozer, backhoe and front loader, the blades can be fixed and held in several different positions.As far as toys go, these are a little pricey but even a three year old understands from the detail that these are different that the coarser, simpler $5 - $10 equivalents. These clearly look like the "real" things. We've all had a lot of fun with these.This was the first of the four Bruder construction toys we bought and likes so much that we added to the set. It's also probably the most easily broken, especially the detailed parts on the backhoe, but so far, despite some aggressive assaults, everything's held up and continues to delight the kids.
