Gelzone Garmet Belt after TT

Has anyone used or heard of the gelzone garmet belt with silicone sheeting. I'd love to hear your thoughts on this product as I'm preparing for my tt at the end of the month.

My PS is providing my with a simple binder but I'm looking for a few spare b/c I know I will be wearing them for the next few months.

Also, has anyone used bio oil for their tt scar?

Thanks for any suggestion :)
