We use a similar at the work, so I searched a similar one for my son, but first we bought a digital microscope which was very good quality but we could not use for soldering.
I searched over the net and finally I found the Vevor site with a discount price for the scope, I saw on the aliexpress Vevor site that there are 7 pieces so I didn't hesitate and bought one here.
I absolutely satisfied with the product, everything in the box, I got it in 3 days! Only the cover is small, and the instruction manual doesn't belongs to this type.
