Key handle extends between stowed position and extended use position. The lever has a locking knob on the inner tube that fits into a hole on the outer tube to lock in the extended position. Unfortunately, the size of the locking button is too small for the depth of the hole, resulting in the key shank tending to fold during use. This has been observed on two units ordered so I have to conclude that this is a design flaw and not a manufacturing defect. Given the many positive reviews for the product, there may have been adverse changes between production runs, so you may be lucky with your order.
