## Description

Review: All Geared up - Good quality and good selection
Review: Disappointed - This looks like a really nice set, but it was purchased primarily for the tred pieces, however there doesn't seem to be enough of a specific size to do 2 (e.g once in each side of a tank) and the quality on the larger treds is very poor, 4 broke in the first day. Solid pieces like the cogs and rods seem pretty study and the wheels are ok, although bit up to lego quality
