The metal used all TOOLS is not hardened and bend at the slightest application of force. Screwdriver rotate without sehends blind because they are scraped by the screws.
The biggest blast is the tool to dismantle the pins. First of all it is, lashed the bracelet with the pen there. Flying blind, you can not tell how the tool engages the pin. In fixed pins of the pin is more stable than the plastic that breaks pretty quickly. The pen design driver is of course also not hardened and bend jiffy.
0 stars are not possible, but would be appropriate here. The kit is cheap, not cheap, more a child's toy and just near it to be a tool.
