Cheap and fully conforms the specs. Good quality, easy to solder, small outline.
Cons? Are there any cons?
Don't expect it to give you the specified 20 mA indoors, in artificial lights (unless put close to a strong lamp). But if you already had solar panels, you know that. My panels have that "wiring" on the sun side parallel to the long edge, and the soldering points on the back are in the middle of the PCB. Not a big deal.
Buy this one if you need a solar cell with these specs. It won't recharge a car battery but it can be used to power solar garden light or toys (especially if you connect two panels serial to get 4 volts).
