sungwoo Foldable Silicone Keyboard USB Wired Waterproof Rollup Keyboard for PC Notebook Laptop (Black+Grey)

I initially bought this for myself as replacement keyboard for my laptop since some of the keys weren't working. I would disable my keyboard and then just slide this right over the laptop keyboard as thought it was just a cover for them, and it would've worked smoothly if only I knew how to disable my keyboard keys. However nonetheless this is a great product. I ended up giving it to my grandparents and they use it on a daily basis for their computer. All of the keys function as they should. It is very portable as you can see, being able to roll up, fold, and such. The installation is very simple, just plug into you're device and instantly works.

TYPED THIS REVISION ON IT AFTER HAD ABOUT A MONTH, THE SPACE BAR WARPED AND THE LETTER 'N' REQUIRES ADDITIONAL PRESSURE TO GET TO WORK. NOT USEFUL FOR MY TYPING SKILL LEVEL>>I use the keyboard to have multiple PCs running on my small desk simultaneously. The keyboard folds up to move out of the way easily, and can be placed over the laptop keyboard for use when necessary. It does require a pretty positive key press on some of the keys, which causes me to omit letters when applying my poor typing skills (hunt & peck with limited touch typing). I just roll it up when I switch from he desktop to the laptop. I scored "portability" as 5 stars, but since it is a USB wired connection, it is not really "portable" like some of the bluetooth keyboards I have used. It IS "portable" in the sense that I can easily move it out of my way & roll it up into a compact form.

So far, this wired keyboard works as expected. If you are looking for a lightweight, portable, rollable, full-size, wired keyboard, this on will do the job. For normal Mac uses, the Sungwoo works, although the key placement takes some getting used to. But if you need to reboot a damaged computer or input Mac commands, the Mac does not respond to all commands because the Sungwoo is designed for Windows computers. Maybe this is true only on some models of the Mac (e.g., older macs) but it is annoying, since one advantage of a wired keyboard is that it is active even if the computer is dying, whereas a BT keyboard might not be recognized by a dying computer.

I bought this keyboard in 2016. Although it wasn't the best for typing and the tactical feedback left a lot to be desired, it was still a functional and more importantly, lightweight, portable and easy to store keyboard. Had no issues with it for years. After having it rolled up for the past couple of years, I took it out again for some use and I realized most of the keys no longer work. It still receives power and many buttons work but a lot of them no longer do, such as the majority of the letter keys. wasd for example. So I cannot recommend this as a long term product. If you do purchase it, It probably is best to never roll it up, that may be why mine is no longer working.

Mostly works well. Even though I have small hands and am used to using a full sized keyboard most of the time, I would have problems with this keyboard accidentally hitting other keys because it is relatively small. If you have to use this on a consistent bases, you'd probably get used to it; having used it for a week, I'd rather not use it again unless I just have to. The only real issue is the backspace key doesn't seem to register unless you push exceptionally hard on it. Very frustrating when typing and having to learn a new keyboard where the backspace doesn't register with the same ammount of pressure you use for the rest of the keys. Could be a defective product or it could be design. Not sure, just what I encountered with this product.

Nice keyboard, had to get something compact to carry with me at work as ketboards go missing from work stations. Now I don't have to worry about it.

OK this review is actually based on the purchase of ten of these that I shipped to students for a remote class thing. This is both based on my own personal feedback and their aggregated feedback: Out of ten of them, the number row was nearly non-functional on two of them, and sticky/hard to use on two more of them. I'm not sure if a different type of button was used there or what but it is weird that that particular area of the board very consistently had a problem. The other keys generally worked...just in their own special way that I don't particularly like, however I recognize that people like different keyboards. However out of the ten high school students who were using them, they all, except for one, said they did not like using these things...several going so far as to say they hated them. If you are a fast typer or a touch typer, this keyboard will be like trying to sprint through a pit of mud...it will slow you down unbelievably. The number of false-hits is really high. In the case of a hard plastic key, pushing at the edge or off center is almost always sufficient to bring the whole key down...in the case of these things because the keys are bendy material, off-center hits or not pushing hard enough will often not succeed. You really got to have a head-on collision with these keys. Reminds me of old typewriters. The right shift is too small for my taste when I was using one...kept pushing the up arrow or then kept overcompensating after a while and pushing the ? key... I really need a shift key that is two-letter-keys in width to be happy. So take these thoughts for what it is worth. Now...if you are a slow typer and/or one finger typer who looks at where your'e pushing, this will probably be a fine keyboard. Also after getting these all back from the students I actually decided to dunk one of them in a full sink and see if it still worked. And it did! So they are waterproof, and they do roll-up which everyone has a knee-jerk "wow that's cool reaction to"

I really like this keyboard! Only complaint is the wire that come out the top of it looks really cheap, and it wants to bend sharply, which leads me to believe that wire will be the first thing to go out. So I've secured my wire with various attachments that I added onto the thing, to keep the wire from bending too sharply. I wish they had designed that wire to not be able to bend so sharply right where it exits from the keyboard. But other than that, the keyboard itself works perfectly and I wrote this text with the keyboard, and I'm typing this pretty fast. I do have to press more firmly on each key as I type because there is no "click" to the keys, so the only way to ensure that your press registers is you must press slightly harder than normal. But other than that, it's great. Totally silent.
