Great Product
I used two of these in a solar powered garden light project. Two are able to charge 4 Ni-Cad batteries on a sunny day. They work exactly like expected, the only down side are the solderable foil strips on the back. The strips bend and rip fairly easily when the wires attached to them are moved around, but a little glue from a hot glue gun solved that problem.

A great little solar cell. I use it to manufacture solar radios.

Nice Cells
These are some of the newest solar cells available. The Solar material is deposited on glass, and then the whole thing is coated with a plastic resin. Before EVEN TESTING these cells, allow them to sit in full sunlight for 3 hrs or so, and you will find that they will produce approx4.5v (open circuit) and 75-80ma (short circuit). 4 cells wired in series will charge a 12v battery pack @ 50-60 ma. The leads (solar tabbing wire) are VERY FRAGILE. If they are taped on the back, leave the tape and solder your leads to the exposed part of the tab wire. If the lead breaks off, you can scrape the resin coating of of the face of the cell (where the leads attach and glue another piece of tabbing wire directly to the face of the cell with a highly conductive epoxy or glue. As long as the lead touches the UNCOATED face of the cell, it will work again. May lose a LITTLE of the output, but the cell will be saved.

great value.
As echoed before, don't fold back the tabs or remove the tape. Instead use a braided wired to couple the cells together. You do this because the expansion and contraction of the cell in the sun can snap the flat leads, and a thin low amp braided wire will give the array a very long life, and help to avoid disconnected cells. Most of the cells I received averaged 3.9V @ 55mAh in full noon sun. Very happy so far.

easily rendered useless
These don't come with instructions, so I stupidly removed the tape and began to solder wire directly to the foil contacts and they snapped right off. I was unable to chip away at the area covering where the contacts once protruded, like another comment suggests. Unable to use. be careful with these.
