Top coating previously, overall unfortunately lacking

The pan itself looks good, is easy to handle, and has so far (about 4 weeks in use) a very beautiful, scratch-resistant interior with very good non-stick effect. What makes the pan but almost useless, are two facts:
1) The pan bulges enormously when heated, as already several pros reviewers have noticed. Such a bulge really extreme, and I had yet to see in any pan
2) The bottom of the pan (bare aluminum) wears out - unfortunately, to the chagrin of my induction hob. Its glass surface is for the use of the pan almost silver through the aluminum rubbing the pan. The extent of this abrasion damage the induction field, I need to clarify ....

Thus, the pan is flying out of the kitchen - I'll use for grilling on outdoor gas grill.
