I'm sure someone from the community tried it and will be able to say more about this device.
I'd say you can try it, just perhaps purchase one and test it before committing to a larger number.
It will also depend on the kind of content you will want to display on it.
It's not on our recommended android devices list, so we obviously don't recommend it, but as I said it's cheap so you can try it.
In general those cheap devices have a lot of issues, overheating/crashes playback problems etc so if you wish to stick with it feel free to do so, just please test on one device before you buy more of them.
