Q: Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.

A: Negative
****
Q: This set of assorted short tracks is hard to avoid if you want to create a track layout of even an intermidiate size. The male-male and female-female pieces will provide a dramatic increase in the number of layouts possible as you can now overcome the problem of curves returning to the starting position.This is a must-have for any Brio enthusiast.

A: Positive

Q: I play this cd over and over again. I use this when I'm going for long walks and te time just fly!
