    I just received this product. It looks great.

    I have not used this yet but I have no doubt this is a quality product. I do have one suggestion though.

    They only ship via the post office. I live in Indiana and track all my packages. The package went from Nevada, to Indiana. Then from Indiana to Ohio. Then shipped from Ohio back to Indiana. I know it's not the company's fault for the delay in shipping. However, if they offered a choice, I would use UPS instead.
