ordered 2 clamps the same. only sent 2 different ones, trying to get it sorted was a nightmare. Speedy delivery but took days to answer emails, i prefer phone but you need a like minded person other end, First told directed to wrong department and customer services would call me. no phone call. called again told as internet sale they could not deal with it. Back to emails, spent hours trying to sort simple problem out, company lack product knowledge and can not resolve simple delivery issues. Would never use again
