Bluetooth® Pocket Keyboard Case for iPhone® 4/4s - Black

Do you love your Apple iPhone® 4, but sometimes wish you had a physical keyboard for texting, like some of the other phones are the market? Wish no more, because Monoprice has a case with a built-in sliding keyboard designed for the iPhone 4/4s!

This polycarbonate keyboard/case fits onto your iPhone 4/4s and provides protection for the back and sides of your phone. Cutouts on the top, bottom, and side provide access to the buttons, controls, and connectors, while a cutout on the back allows use of the camera and flash. The camera lens and flash are exposed when the keyboard is retracted or extended, so you can always take that candid photo!

The keyboard slides out to the left of the phone and includes four rows of keys arranged in the standard QWERTY layout. A function key allows most keys to serve double duty, providing the less commonly used characters and functions.

The keyboard has its own internal battery and is charged with a standard micro USB cable. The keyboard uses Bluetooth® to pair with your iPhone, so you can even use it when your iPhone is out of the case and sitting in your charging dock! An on/off switch on the keyboard allows it to be turned off when not in use, preserving its internal battery.

The case has a large, single opening on the left side for access to the volume buttons and mute switch, making it compatible with the original iPhone 4, as well as the revised iPhone 4 and newer iPhone 4s.

iPhone® not included!

Bluetooth Pocket Keyboard Case for iPhone 4/4S

Pros: Bluetooth works seamlessly. Very easy to install and configure.

Cons: The keys at the top of the slider nearest the phone are difficult to use due to their close proximity to the edge of the phone.

This gadget works just like it is supposed to, however, due to the close proximity of the upper keys on the slider, it is not easy to use them. If the keyboard slid out just a tad more, it would be perfect. The unit adds a lot of bulk to the phone, but this is to be expected. If you prefer the convenience of the keyboard versus the touch keypad on the iphone, this is a good product. I suppose if you have tiny fingers you might not notice the tightness of the upper keys, but then again, you might not need an external keyboard in the first place.

Not so great quality, too heavy to be useful

This keyboard has solid construction in terms of the attachment to the phone and the sliders in/out. However, one of the keys stopped working after a short while. I found it too heavy to carry every day however, if you are looking for one of these keyboard, it's a good price.

Pros: More screen for viewing
Connects/syncs very easily

Cons: Must turn it off & on in order for the battery to continue to work for more than a few days
If you leave it on, might get 3 days
Small battery

This is a great invention!

p.s. I rarely rate 10

Good product, not perfect

Pros: Decent size keyboard, a magnitude more friendly than trying to use the on screen keyboard!
Good layout of the buttons, with useful FN button to access less frequently used things like numbers.
Working great (when battery is not dead - see Cons)

Cons: Power button was meant to help avoiding discharging the battery, but it is easy to flip it "on", so it happens by accident really often when I'm slipping the iphone into my pockets
Battery life not very good, have to charge this every day, but might be because the "on" is often switched by accident when I pocket this.
Relatively bulky, makes the iphone more than twice as big (thick), and that much more heavy. Not that big of a con for me, but that definitely turns off most of the people I showed this device to.

I was real happy to finally be able to type messages and emails faster. The keyboard really achieves that objective. The only big con for me is the limited battery life, which means I have to keep this plugged in every time I can.
