[EX Q]: I've only worn this for a day so far, but I love it! I still have a little bit of a tummy from the birth of my son 8 months ago. This really holds you in, its comfortable and I don't think it shows through your clothes! I highly recommend!!
[EX A]: Positive

[EX 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.
[EX A]: Positive

[EX Q]: I received a different adapter so I cannot really tell you about the Macally adapter. I received an adapter from Inspire and it does not have the longer cord, the velcro strap or the led lights. But it does charge my computer and it arrived quickly.
[EX A]:
Negative
