Product review (4 stars): easy to use project power module
Unit works well and is a very easy to use all in one module. However the prongs on the back are not very suitable for soldering to. You really should get medium side spade terminal lugs to wire to this module. I have soldered to it, but the plating is not designed to solder to and it is difficult to get a good bond. That and the plastic tends to melt if you spent too long trying to get that bond.
The spade lugs in the back are not standard American width, they are about half width, so you must buy female lugs that match the smaller width to get a tight connection.

I would give this a five star rating if the plating was tin, not chrome style, or it came with standard lugs, or if it came with crimp on terminals that matched.

6 months later addition:

On re purchasing this unit my next batch soldered fine, so I am raising the star rating to 4.
