sungwooFoldable Silicone USB Wired Standard Waterproof Rollup Keyboard for PC Notebook Laptop, Full Size (Black)

I'll be honest - I did not have high expectations for the performance of this keyboard. I prepared myself for disappointment with questions like "how good could this dinky piece of rubber be?" But I was supremely tired of lugging around a full sized keyboard and the self-imposed embarrassment of having it poke out of my backpack when I was moving from place to place, so this keyboard got a shot.Now, obviously this will not have the same feel as a normal full-sized keyboard, so let's get that out of the way. This is the solution to a niche problem, and keyboard feel and sound will be sacrificed. That said, it it not nearly the amount of sacrifice I expected it to be.Keyboard feel: It takes some getting used to, but I would say this keyboard takes about 5-10% more strength to push the keys down vs. a normal keyboard, but I think that's because when you're not entirely precise, you're pushing against the harder outside silicone of each key (diagonally in to get down). If I'm very precise and push down in the center of each key, then it's very easy to type, and short of the feel of the silicone, the effort feels like laptop chicklet keys.Keyboard sound: obviously the silicone is going to mute al your typing - you still get tapping noises from your fingers hitting the keys, but there is no mechanical noise of the key switch being activated. If I type slowly, it's entirely silent.Keyboard layout: Layout is incredibly important to me. As a power excel user, I need my function keys (F2,F4) to be dedicated vs. shared with things like volume and contrast. I also need the full number pad, which this has. Last, the Home/End/PgUp/PgDn buttons are also dedicated and in a good location.We'll see how durable it is - for now, I'm just folding it in half and dropping it into my backpack, but I imagine at some point things will start to wear out between the silicone and the sensors in the keys.Also, just to be comprehensive as I can, this keyboard isn't 100% fully flexible in every configuration - there is a section where the logo is (where the cable comes in) that has the controller and whatever other hard things that need to be in there, so that part does not flex. That means you do need to exercise some minor caution in rolling it up and transporting it.

I've had this for almost 4 years, using it about twice a week. I'm now having issues with it and will buy another one today, to replace it.

Works well but you need it on a hard surface

Works great for mobile work in large worksites but if you roll it the keys will stop working

I bought this for my grandchildren's workstation. I purchased this keyboard more than nine months ago and it still works great. You can just wipe it down with a wet cloth and it's good as new.

Im sorry to say this but this product sucks. I called Amazon about re sending me the product because i like how quiet it is. The problem that are going on with the first one is that it only lasted me 3 days. The numbers on the keyboard not the number pad 1 though 4 stopped working. I really didnt know why so i called Amazon to figure out if they can send me a replacement. The person that i was talking to was very nice and helpful. The Amazon lady did her troubleshoot and other this by calling the company that made this keyboard but nothing. So she replaced it and arrived and so second keyboard well everything works but not my space bar. This isnt a product that should be picked by (amazon choice) this keyboard is garbage "DO NOT BUY" no JOKE DO NOT BUY because you will have this problems with this product.FYI, I only bought this because my keyboard on my laptop is Mechanical so my typing gets annoying at work. As well when you buy this product it comes in small box.

Very nice keyboard

The key board stopped typing the letter u and I. I have only used it for about 2 months. I have tried all the trouble shooting recommended and it does not fix the problem. It also randomly types the number 8 when I am using the key board.
