Doogee T30 Ultra, T20 Ultra and T20mini Pro tablets announced - GSMArena.com news

Is this a reputable brand? Never heard of them before. I'm thinking about replacing my 10" Kindle Fire because it lags a bit and struggles with the Crunchyroll app. I mostly use it for reading manga, and it's great for that, but I'd like to be able to watch shows without any hiccups too. Wonder if the 11" of these would be a good replacement.
