What's wrong with LRP'S SPX Stock Spec

[Bimdapogs]

I notice a lot of used SPX ESCs showing up on RC forums being sold for a lot less money that what they retailed for. And I have a pretty good idea of how much used stuff go for, but 30-40% of retail?

So, I'll ask, what's wrong with this ESC? I'm about to buy a couple of them and I'd like to know if there are issues with this model.

Any help is appreciated.
