I believe this a very poorly designed setup at least as far as installation is concerned. I thought it was kind of impressive in a silly way that it came in a cardboard box but quickly noticed that whoever is selling this pays attention to detail and the box was just an indicator of a seller caring about their products. Pictured are this years which he has been wearing for a month and already they are broken. If I accidentally loop it over itself its usually a two second fix. Personally, I like it the way it is so that I can opt to have the extra usbs attached when needed but generally not worry about them. I love Logitech and have been buying their keyboards and mice for years, starting with wired and now wireless. Whoever invented this thank you thank you! Größe fällt normal aus. I know the price point seems a bit high for a pair of slippers but given the comfort level and hopefully the durability you cant go wrong spending the money on these. When it was time to replace it, I thought I would try this Remington shaver and am very pleased with it.
