[Q]: I bought two sets of these. They're priced at $9.50. But, when they arrived, the price tag still stuck on the item says $2.99. Nice way to hide your "shippign cost" ($6.51) from your customers! This company goes on my "Never Again" list!
[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]: Complete waste of money. All three sizes pushed my Jawbone ICON out too far from my face to make contact with my jawbone.I know my ears stick out ... I am not dumbo though. This was a waste of money for me, thankfully they were only 10 bucks.I went back to the ear pads that came with the ICON... Is stays in for a while as long as i don't move... Not quite battlefield worthy as JB claims...
[A]:
Negative
