The rule on Ebay is the same as everywhere else: "buyer beware". No matter what you're bidding on, you have to read the listing carefully before you bid, and questions if you need to clarify something.
That said, every listing I've seen for these cheap 225 diode panels has explicitly specified 14 watts NOT 225W. So unless you just blindly bid without actually reading the listing, I don't see how you're going to get fooled here. Doesn't seem to me like the sellers are trying to trick anyone.
In terms of the actual merits of these panels, I've opened a thread specifically on this question:

Without ever having tried one, it seems obvious to me that with only 14 watts of output (let alone 14W divided between 225 individual point sources) that you're not going to get much light intensity.
Even stipulating that LEDs are three times as effective as HID lights on a per-watt basis (and that's debatable), you're not going to get very far with only 45 watts of HID either. At
best a small 14W panel like this is going to be OK for one small plant and not much more.
That's OK. Believe it or not, there actually are people want to grow things that are NOT cannabis! If you just want to keep a small houseplant alive in your office, I'd imagine something like these 14 watt lights would be perfect, since they use little juice, generate negligible heat, and ought to last a long time.
