Default [Q] Tagital Tablet

I bought this tablet and it has turned out to be very very slow. Im not sure if its just the tablet of the rom. so I was thinking of looking for a custom rom, but I can't seem to find any. Here are the specs. Is this just a slow processor and a waste of my cash?
Where can I look or find the way to Root this tablet. I downloaded the app to check it and it says its not rooted. I like the rom, very bare, no bloatware.
