I just received these and was finally able to work on the device that required a spanner screwdriver to open. These seem to be well made. I like that they are actually screwdrivers instead of just the bits and a shared hex driver. That is much more convenient when the screw is recessed in a deep well. These seem to be well made, the size I needed fit my screw exactly. They are exactly as pictured. I cannot say if they handle high torque or not since my application did not require that. But they feel as if they are pretty strongly made.
