I have received this product for free for my unbiased review. What I did like that it had 3 interchangeable rollers in sizes,0.5mm , 1.0mm and 0.5 and they come sealed in their own compartments. These are used for regenerating collagen and firm my face up and it helps keep my soft and silky after it heals after using it. Also it helps any products work better. What I don't like about it. The handles and rollers are encased in white plastic. Also they are a little difficult to snap into place as well. Also If I am giving it to someone as a gift I don't think I would because it looks cheap.
