Product Quality/Appearance
Dear All I like your ease of usage website. I am reasonably happy with the product. It appears to me that some of the wrist bands are not made of high-quality silicone. I write this because the black silicone seems to exibit a grey cast upon use, above and below the wording on the front and back of the wristband. The black does not remain strikingly black but has a greyish cast. Why does that happen? I would love some answers. Best, Andrew J Guinosso
