They are scammers, don't buy from them. I have a faulty product. They offer a lifetime warranty as advertised on their website and after contacting them via their email they emailed back to say I could have a replacement or refund, so I opted for a refund but I have never heard from them since, despite contacting them continually. The company that operates the website is listed on the website under "impressum" - you can see their company name and address and if you google there are 2 people who head up this company - you can research them and get in contact with them and request that they suspend the website. Don't let scammers prosper.
