Query: Bosch PS10-2 Issues

I bought this at the big orange home improvement store and really wanted to like it. The tool felt very heavy-duty, and the power seemed to be more than adequate for my purpose of installing cabinet hardware in tight places. The batteries charged very quickly. However, I noticed when I released the trigger, I could see a flash of light in the motor through the heat vents by the handle. I don't know if they all work this way, and assumed that they did, so I proceeded to use the tool. However, after I completed the work (I was driving the last screw), the driver stopped working in the forward-drive mode. It reversed just fine. I don't know if this had anything to do with the flash - maybe something burned out - but I had to take it back for a refund. I chose not to get a second one.
