Unfortunately, I was unable to purchase product... After going on the website and placing my order using my Amex card... one of the options given, my order was twice rejected... Contacted the company who rang me back and said sorry no Amex... I asked if they could take my order over the phone given the mess around they had caused me.....Nope.. we don't have any facilities to do that......OK thanks for nothing! .... It's pretty easy to go buy another brand..there are so many alternatives out there......and most likely I can use my Amex card.... my card of choice....... again...thanks for nothing OPTISLIM.....
