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

Saved me a ton of money!
I travel with my laptop and about 4 days before a trip the keyboard began to misbehave. At times I was not able to login making the laptop useless. Smile.Amazon.com to the rescue! I received this in time for my trip and it works perfectly with my laptop. As other reviews have noted, the keys do require a more definite stroke, but to me this is an advantage – I now have fewer ‘lazy-finger’ errors. The keyboard must be placed on a hard, flat surface to work and when changing working environments such as cold (car storage) to warm (workdesk), the keyboard needs time to adjust. The temperature differential between inside and outside the silicon keyboard caused the keyboard to appear slightly inflated. The unit worked fine but felt funny to the touch until the temperatures normalized. This took no effort or action on my part. Just a little bit of time. My built-in keyboard is currently behaving, but I will keep this in my bag for a backup. Highly recommended.

Better than expected! Good for traveling excel nerds like me
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.

Bought this keyboard few months ago. The keyboard is now wavy and the numeric keypad doesn’t work anymore. Really disappointed in this product. Plus, the wavy thing makes it really hard to use.

Why such a low rating?I bought one. Returned it and got a refund. Bought another and got to return that one as well for a refund.Why?First. Key Mapping errors. There are about six keys that show a different character to what is on the key. I ordered about 6 weeks apart. Did I get two from a bad batch? Just be aware.Second. It is definitely a US setup. Not made clear on the product description. The ‘3’ key does not have a ‘£’ option. Why ship a US keyboard to the UK? Again, be aware.Third. I knew it would take some typing adaptation for a silicone keyboard, but over several weeks I found it was too inefficient. Example the ‘space’ bar. On a standard keyboard you can hit the space bar anywhere and you get a ‘space’. On the silicone keypad you have to hit the long space bar almost exactly centrally and very deliberately, otherwise no space character registered. It really proved to be inefficient going back to insert missing spaces. Be aware.Cleaning. The keyboard is sealed (spill-proof) and can be wiped down. However, the nature of silicone is that it attracts dust and debris and it sticks to the silicone material. I think that you will end up cleaning the silicone more than a standard plastic keyboard.My recommendation. Buy a min-keypad, with no num-pad. They are really small and light and will fit just as easily or even more easily into your work bag along with your tablet. Takes up the same space on your desk. Any they work more efficiently. For the same cost.All without the flaws listed above.
