I've bought several air beds from various manufacturers. I bought one identical to this one 1 1/2 years ago. It was comfortable but lost air after 3 months. I justified this as the user may have not taken care. However, I now believe its the brand. This one would not inflate at all. I will not buy this brand again. I've had great life from a better brands.

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.
Positive

As many others have reported, this Zr40 began eating tapes with only a few hours of use on it. I have lost many precious moments recorded on tape because of the tape loading problem.The only good thing I can say about this camera is the bag was large enough to hold my Nikon P100. The Canon is going in the trash.
