I bought the set a Siemens disassemble SL1 and hats for top working condition. Even if it cost with shipping just 9 EUR and comes from China, it does not make the usual "China cheap impression". The box is made of relatively thick plastic, which makes a strong impression, and has a spring mechanism that keeps the box open and the stakes in an upright position. When closed, nothing falls out, there are corresponding locks provided in the lid that keep the bits in place. The bits are all marked so that they can easily sorting in the box again. Use in cordless screwdrivers they will probably not survive, but I have not bought it, too. The bit holder and the extension are magnetic and hold both the bits, as well as the screws very well. If I get SL1 reassembled after repair order, the purchase has already paid off for me.
