I decided to try these before investing in something more expensive like Spanx and I was quite satisfied. I had a snug dress that fit but looked bad on me because lumps and panty lines showed when I wore it. With these on, those weren't noticable anymore.

I've never worn spanx but I'd say these are about the same compression as a pair of control top pantyhose. It was nice to get that control without the whole leg being covered in the heat of summer.

Glad I gave these a try and will definitely be purchasing several more pairs.
