I have all so had problems with UAP Tradelocks. You could not run a business dealing with these as it will make your own business look bad due to having to tell your own customers that there part has still not come. I have tried to resolve a simple problem with them that went on for so long i just gave up and wrote my order of as a loss. plus i am now on my 3rd letter box camera and have now brought one from maplins as i just can’t deal with them anymore or there cheap crap imports, Gave them the benefit of the doubt 3 times and each one was a epic fail, I have been fair with them but 3 out of 3 bad experiences is enough for me to make my mind up,
