Be prepared to modify
The tracks themselves are very nicely detailed. They don't snap together easily; I had to build a jig to assemble them. The worst surprise for me was that the tracks do not mate with the Tamiya M113 ACAV's drive sprocket. The sprockets do not fit into the slots on the tracks; I tried thinning the sprockets and in the end I ended up clipping the teeth off where the track came in contact with the drive sprockets. I guess I'll just cover that area with a light coat of mud when I put the APC onto the base. I recommend this item with reservations.
