Query: Very flimsy! Overpriced!

I also had problems with the battery connection on this product. It took my engineer father two hours of playing with the connections and finally jerryrigging it to get the light to come on. Also, the on/off button doesn't stay pressed down to keep the light on. In general, the construction of the unit is just cheap; it's lightweight plastic that I expected to be much heavier. The images look okay in the viewer, but I was surprised that so much of the viewing area is taken up by the border of the slide. If you have old slides at home, there aren't a lot of other options for viewing them. But this product isn't worth more than a cheap flashlight.
