ebay air tool set

I found this air tool set on ebay for a good price, i want to know if any of you guys own it or saw it in a store or had any type of experience with it. Is ita good deal or is it cheap and useless? The only reason why im questioning it is because alot of other people on ebay are selling it too so you know how that is. heres the link
