Build quality is good and it almost match the 3W/6V specification at ideal conditions. I have ordered 5pcs for some robotic project and they come well packaged in bubble wrap and quite fast. If you cut track on the back side you can re-solder the cell in different way to double the current sacrificing the voltage (see picture)

It's perfect for small projects, DIY, chargers, arduino and others. Deliver 6,0-6,6 V. but it's very difficult to get more than 2 w
