Looks nice, but the pricing is steep, and the subscription model has drawbacks as other commenters have mentioned.

Perhaps consider a limited free version, say 1000 rows and 10 tables as a limit.

The positive side of this is that it will put it in the hands of many people, most of whom wouldn't have bought it anyway. This lets you get more feedback and find more bugs. A fraction of them will like it and tell their boss to buy the paid version. Do not provide support to free users, it will eat your time.
