Oak infusion spirals?

[astroud83]

Does anyone know anything about Oak infusion spirals? I am interested in trying these as an alternative to purchasing an oak barrel. Just curious if anyone has any experience with them. Or has anyone tasted home-made wine where someone used these. Here is the website that sells them to give you an idea.
