TechSilver - very good. They responded very rapidly to a question I had about a product. However, the reason I needed to contact them was because I had bought a High Visibility keyboard which was described as suitable for iPad and PC. Unfortunately, the keyboard layout makes it unsuitable for use with an iPad unless two of the keys (shift-2 and shift-') are relabelled. Even more annoyingly this thing cost over £60 - the exact same item with normal keys is available from many sources for under £20. They offered a refund, but I will first check with the intended user to see if they can cope with the discrepancy between the key labels and symbols displayed.
