Wow! This is a simply massive set of tools at a ridiculously low price, given the range of sizes that are included. And, surprisingly, the tools and storage wallet seem well made and finished to a high quality. Unfortunately, our tests threw up one or two problems. The 10mm open-ended tool's head is too small. And, while both it and the 14mm spanner passed our loading tests, they eventually failed by cracking and shattering.
