I bought these hoping that they would be easier to assemble than the Ryefield Sherman tracks I had gotten frustrated with. I looked at the instructions on the back and thought Oh, that is way simpler! This will be breeze. Wrong. Don't get me wrong, the detail is great. But the assembly, no. These track pieces are supposed to just snap together. Well, the don't. I broke two links before I realized they don't actually snap together. The plastic is so soft it just snaps if you apply any pressure. You're not supposed to glue them, but they don't hold together if you don't. I couldn't get more than two links together at a time. How am I supposed to link up 74? Scoff all you want, but this is not worth the hassle.
