Query: My worst Amazon review, ever..

I read the bad reviews on this & decided to go used from an auction site.I still spent more then this set is worth as it went into various recycle bins 2 days after the purchase.My son was SO excited to open this on his birthday only to find mom had to work over an hour to get it stable (using sure-track) The trains get stuck on the way down & you need to push your hands in to move it..this knocks down tracks & the crying begins...do this for non stop for 2 days...in the trash it went.I plan to try another spiral set before next Christmas. This time I will test it out in private so I can avoid upsetting a toddler who still thinks I should be able to make even a piece of junk work properly.
