It is a nice tool kit, for a good price. I got them as suvenirs for an internal engineering conference. It comes with the 4 bateries. It is a little messy inside once you get them, so you will have to organize the bits but not a big deal.
The process was very quick and easy. Just send them the image I wanted printed on, and within a couple of hours I had the proof at my inbox. I confirmed the order the same day.
