The OP purchased these from us and contacted us 3 months after they were received to tell us that the wrong product was in the box. We offered to exchange the incorrect product for the correct one. When the product was received they were in the correct box but it was clear that they were not new, and were in fact used clamps. You could clearly tell by the color of the anodizing on the clamp versus the tube holder.
We informed the OP that we would not be replacing the product as they were used.
We are more than happy to go out of our way to aid our customers, offering exchanges after a 3 month period, but we will not be taken advantage of.
