Product itself is good but I made myself scammed with a promotional offer. By buying the site, Dujardin had to repay 50% of the product (I bought 2 knowing that one would be reimbursed), we had to provide a lot of papers including a flyer to download from the site Dujardin. Now the site no longer offered the coupon download while I had received my package the day before the end date to buy a thousand terminals. So, I sent all my documents with a letter saying that I could not download their flyer it is not offered on their website. Dujardin response: "we can not pay you because it lacks the flyer." A shame !!!
