The device performs reasonably work is asked. I made a support 40/50 cm high, allowing the device away from the object. You can take pictures of your stamp or a large-format coin in their entirety. Of course, the focus should be turning the ring of the device, but once this is done, as can be triggered from the keyboard, it does not touch the support: so there's more shake. Led by the lighting is adjustable to extinction, which can avoid overexposed images. It is a small device that is honest work.
