If you're new to tablets, then I suggest you purchase your first device from a reputable electronics store - preferably a national chain - they all have a return policy. For around $200., you can buy a decent, brand-name tab with a warranty and support.
If all that you're looking for is a big screen and are not concerned about customer service, then certainly go for the Chinese generic tab. But, if something goes wrong and your girlfriend gets angry, don't blame me if you get sent to the doghouse.
