This small, handy tool collection contains all the important bits, nuts and adapters that you "times on the fly" needs. I am engineer working abroad and do not want a lot of (heavy) tool with lug around with (air travel). For this tool collection is ideal. All parts are protected against Heraufallen but still in need within easy reach. The fact that a "box" around it is missing, the footprint is as small as possible. The Ratchet looks very delicate from, so not suitable for repair of marine diesel but for my purposes perfectly adequate. If that also is so, I would recommend this product without restrictions.
