NOT a computer, as listed and pictured, but an empty BOARD

This seller's other items state BOARD in the title, but this one states computer, and lists all of the features of that computer, so one would naturally think it's the computer, either kit or assembled *as shown in the picture*.

IT IS NOT. It is a plain, overpriced 2-layer PCB. The only note stating it's a PCB is hidden under the Watchdog item description.

I would advise staying away from this seller due to shady practices.

Response from Retro Computer Dojo | April 9, 2023

Dear Randy,
I am sorry you were not satisfied with your purchase. The description for the PCB board was in the description and not hidden. Hidden means to hide, withdraw or remove from observation; cover or keep from sight. If you can reference where the board description was located, your argument is invalid. The statement on the page was "This PCB board does require some SMD soldering. Please note: This is only for the bare PCB board; no parts are included". Moreover, you never asked any questions. I would gladly refund the purchase if you so requested.
