+1 for Dr Pete.

The downside risk is high with no limit (i.e. you could die when the bike breaks up while a truck overtakes you), the probability of the thing breaking in my view is something like 80%. Multiply those together and you get a lot more downside than the $150 you save.

If you can't get your money back, chalk it up to experience and hacksaw the frame apart so than nobody tries recycling it.
