Example Input: Had high hope on these. Think that it's such an awesome idea. However when you put it in use, it's kind of flimsy. Unless you have pure soil you can dig, if there are any rocks, roots, wood chip... Good luck to your fingers.

Example Input: LOVE LOVE LOVE!!!! Everyone that sees this wallpaper absolutely loves it! I was able to put it up by myself without any help. I've never used any kind of wallpaper before. It was really easy. The only annoying part was having to match up the print, but you have to do that with any wallpaper. It's great quality! I was easily able to peel it back off if I needed to fix a spot. I have slightly textured walls and it wasn't a problem. It's been on for three weeks now and is still perfect. Now I want to put wallpaper more places. So glad I bought this!

Example Input: This has got to be the best keyboard I've used in recent years and I've been through countless Keyboards over the years. The Ergonomics of this keyboard design is Excellent! I am blown away at how comfortable it is to use and the factor of the whole thing is just so sleek; it almost look like the keyboard is floating on your desk. I haven't enjoyed typing like this in years. The feedback of the keys are responsive and my fingers just fly with each loud click coming from the keys. This keyboard is a right choice 10/10 !!!
