Anyone used "The Bean" exerciser? It's for abs.

Hi, It's been a long time since I've posted anywhere on here. I just ordered The Bean a week ago and it should be here in a couple of more days. Just wondering if anyone else has tried using it. After 2 C-sections and a hysterectomy over the years, I'm afraid I've really neglected keeping my belly muscles in good shape. But I'm ready to remedy that and I'm excited about getting my Bean and getting started. Let me know if any of you have tried it and if so how you like it. Thanks. :-)
