Product, nothing to say: practical hyper keyboard and case covers your tablet even if it is a bit messy. For cons, I purchased this product in late November and I had to get a refund offer 20. Unfortunately Logitech has entrusted the management of this operation in CUSTOM SOLUTIONS. Let me explain. I sent them my complete file on 05/12/2014. On 17 January 2015, I received a letter that I have not sent the "copy of my sales receipt / invoice or it is unusable." Knowing that I bought this product on AMAZON, I can hardly get a receipt. I sent them the status of my order, only proof of purchase that was accessible to me To My Account AMAZON but on which it is actually not said "invoice". I ask a "real" bill me AMAZON which transmits extremely fast, which I congratulate them. On January 20, 2015, I send this bill in due form by post because CUSTOM SOLUTIONS does not know the benefits of email and the miraculous ability to transmit these elements attached. And since then no news. I saw myself not too worried that the company had already 1 ½ months before sending me a letter of non-compliance but in the meantime, I filed two claims folders home where again, they dragging their feet to pay me. When I send them a message on their website, a ticket number appears but I do not receive any confirmation email and no response to my messages. Makes you wonder what they do with that money ... I do not understand the big brands to trust to this company.
