Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
Simple construction, lightness, good plastics. Low price.
Cons:
The spring of negative pole is not strong enough to push the battery against the wall of the shell and achieve a balance contact of the positive pole. Electric cables are really thin. One of the welded joints between rivet and wire broke during assembling.
Other:
The 18650 battery is closely fit.
Bottomline:
Needs a stronger spring, and would be better to have thicker wire (if possibly, with better welding..)
