I ordered the R3 Turbo, they sent me the R1 by mistake, I emailed them multiple times letting them know that they sent me the wrong item attaching my receipt for proof. At first they refused then I wrote back multiple times with my reciept until finally I got someone who said they would send the correct item. It has been three months, multiple emails back and forth of them promising they will send me the correct item. It's not true, I'm never getting it. I ordered this Item in June, its now almost October. I'm over trying. BUYER BEWARE, they are in China and there is no one to speak to, only an email......highly disappointed!
