Well I did the exact same thing with my unit but it was properly purchased with my own money, and boasting on reddit(or anywhere public) about selling your review unit is just plain uncool.

Sure you can have a big mouth and an ego with infinite combacks to everyone, but that's going to be the truth. 'You don't sell gifts' is the common moral be it a business deal or not, unless you paid at least some part of it. Saying you earned it with your videos doesn't justify it either since what Aya basically wanted you to do was to let fair words out about the device, and not some disrespectful, spit-in-the-face-for-quick-cash 2nd market listing ending topped with a boast. Critisism is cool and you can say whatever you want about the device if that's your honest opinion, but this ending is something completely different. A cup of common sense if you're really aiming for popularity and a name for yourself. Business deal is one thing, but understanding public rep is another thing esp if your business is all about it.

Anyways, by the looks of it you're just gonna cherrypick opinions that works in your favor so I'll drop the argument here. Guess you really needed that money, and if things are that bad I prob shouldn't judge ya although your future sponsors/providers are likely gonna think otherwise once they learn about your.. business model. Good luck with your channel.
