PLEASE DO NOT BUY ANYTHING FROM THIS WEBSITE THEY ARE SCAMMERS!
Their products are rubbish and fake. I've sent the product back (which they signed for) for a refund as it didn't fit our connections to our CPAC machine and 2 months later after emails promising a refund I am still waiting for $160. Their products are rubbish they have now blocked my email address PLEASE DONT GET SCAMMED!
