ProtoArc Backlit Foldable Keyboard, XK01 Plus Folding Portable Bluetooth Keyboard for Travel, True Full Size External Wireless Keyboard with Backlight for iPad Tablet Smartphone Laptop - Black

Buen teclado, sin embargo es muy delgado y no resistirá en un uso rudo.

I've been using the XK01 by ProtoArc, a device I originally found at a local electronics retailer and wound up buying here on Amazon. But only recently, I started to wonder if there was a backlit option for the XK01. Turns out there is, and this is it. It is EXACTLY the same product as the XK01, but the XK01 Plus has backlighting/illuminated keys. This is a light, folding keyboard that can be paired with switched between up to three Bluetooth devices simultaneously. Charging is done through a USB-C socket on top of the device, and the pilot lamp changes from orange to green when fully charged. Much like the original XK01, battery life is really good, although I imagine use of the backlight will cut into longevity. However, there are three lighting levels (in addition to "off") that you can choose from. All are white lights (so if you're hoping for one of those fancier color-selectable lighting schemes like on a gaming keyboard, this isn't for you). This is a great choice for those times when you have a lot to type or say, and you just don't feel like poking an on-screen keyboard endlessly. It can be used with a smartphone, a tablet, or laptop or desktop computer. It supports all the major OS's - Windows, Mac OS, Android, and iOS - any unit with Bluetooth on it. As far as the feel of the keys, I liked it. Key travel is far better than a membrane-style keyboard, and key response feels good (not "premium", but decent), with enough springiness. It doesn't make a lot of noise when you type on it, so if you're in a situation where silence is golden, you'll appreciate it. And, unlike many other battery-operated Bluetooth keyboards available, this has full-sized keys, meaning far fewer typing errors. Yes, you may have to adjust to the placement of a few keys here and there, but I don't think you'll find the layout to be a deal-breaker. The package comes with a carry pouch, and a USB-C cable. There is no charger included for it, but you can get one nearly anywhere these days, including here on Amazon. I can't think of a better, portable Bluetooth keyboard that's available right now. I think this is as good as it gets.

Here is my review. I have completed my workstation. Pros: Keyboard Model XK01 is folderable, and it is easy to carry it in a nap sack or laptop bag.Comes with battery charging cable. Build quality looks good. Only time will tell the true story. EM05 NL Vertical trackball mouse is ergonomic. Comes with wireless USB-A dongle and battery charging cable. Cons: Keyboard XK01 does not have raises, hence not ergonomic. EM05 NL trackball mouse quality is lacking. Not sophisticated. There is too much plastic. Missing bluetooth dongle for enabling functional office workstation and closed access IT governance is practiced. (No Admin access + bluetooth discovery is turned off). Simple bluetooth dongle will allow BT-Keyboard, BT-mouse, and BT-headset to be integrated at a single point. New business workstations have limited USB-A and USB-C ports. Add-on: UGreen bluetooth 5.4 dongle $20.00 solved my problem.

Do not buy this for a new computer as your only keyboard as you will not be able to login until you pair the device. This requires the ability to login (which requires a functional keyboard) to your computer before you are able to set it up. Which makes this keyboard absolutely useless. I had to use another keyboard (Bluetooth dongle type) to login to my computer before being able to set this one up in settings. Once properly set up and fully charged the keyboard intermittently doesn’t respond, inserts multiple characters, and just doesn’t respond (even if on the charging cable). This device is not reliable and I would not recommend it.

In all honesty, I had very low expectations for this. It was a replacement for the garbage keyboard built into the new Samsung Tab S11 Ultra cover. Turns out this is a really nice keyboard. I highly recommend it if you like to type in the dark and you don't want a bulky wireless gaming keyboard.
