I have to admit that while their products do have many nice features; the overall quality of their products seem to have decrease over the past few years.
I've been using SQL Navigator and Toad for years now. Back in the day, the products were very stable and worked well for me.
I've recently had problems with newer versions of SQL Navigator, Toad for Oracle and Toad for SQL Server.
In my opinion, the new products are unacceptably "buggy".
I hope they begin to put more effort in to QA and quality. They've got winning products, if they could just get them to work.
