Belly sucker

Celia
Has anyone every tried this? I made a post yesterday asking about any good waist trainers or post partum belts. I asked a friend today who had twins and didn't even look like she had kids a few months ago. She recommended this product so I've been looking into it and have seen nothing but good reviews. I'm not into waist training but I'm just looking for something post baby that will give me the pump to get results and get my belly down faster after baby than with no help. 
Any thoughts?
