49-Key Mini Rechargeable Bluetooth Wireless QWERTY Keyboard for Windows/Symbian/iPhone Mobile

Pros: Works fine with Nokia E51 and my personal computer. It's very useful. It is very comfort to transport. But I must find a case(etui) to comfort hold with phone. It's cheap.

Cons: On mobile i have problem with polish signs, because Nokia didn't contain polish keyboard. Build quality might be better.

Other: It is ever useful when you don't like use numeric keypad in cellphone or T9 dictionary.

Pros: Works with iPad, Android, macbook and even my PC with bt adaptor. I can finally play GBA and SNES emu games on my Android without that annoying screen buttons. Awesome feel and buttons are pretty responsive.

Cons: Keyboard layout is weird so there is a learning curve so don't expect to be able to sit down and bt keyboard away on your PS3 fast enough.

Other: Does the job well and is an awesome device. I have seen this in higher price but this is good enough to get me to buy.

Pros: The Keyboard is slim and lightweight, it fits in the palm of your hand, and the keys feel solid to the touch, so you know when you've pressed the keys properly, while it also stops you from mis-typing by accidentally nudging a neighbouring key.
It pairs with my mac, though it took me a few goes to get it to sync up properly (there really needs to be a paper manual included) and all the keys map to the keyboard perfectly, even the symbols are the same!
All the multimedia keys go where they're programmed. the only key that didn't have a proper mapping was the IME key, (which I don't use anyway) which automatically mapped to my Quicksilver install, so that became very useful

Cons: When I received the keyboard its bottom edge was uneven and with a little pressure on it, I was able to separate the case... which wasn't great, it looked like the bottom had warped, but a little super-glue and pressing it back into the right spot, and the issue was gone instantly!
The keys are stiff, and the absence of a win/apple/linux key meant that I had to remap the control on the keyboard to perform any shortcuts that I needed to do on my Mac.
The backspace key also is in an awkward position, meaning that I made a lot of mistakes as I instinctively went for the key in the position that it would be on a standard keyboard.
A lot of the symbols (from the standard keyboard) were in weird positions, so it took a little bit of searching to sort that out.

Other: Buy it!
Buy two, they're fantastic if you need a tiny keyboard to use with a Media PC, or if you're lazy like me, under the blankets on a cold night in bed.
The pros of the device far outweigh the cons, so it's worth it!

Pros: I take some little time to learn how to conect the device on the phone, but is very easy. and works with windows 7.

Cons: the types are had to press.

Other: in brazilin layoutt you can put all accents (acentos) using 'fn' and ç. very cooool!

Pros: Tried with Windows Vista, Windows 7, Linux, Android and Symbian (Nokia E52), and works. Small, light, feels good.

Cons: The effective distance is quite small. If you are more than 3 meters away from your device, then the connection is not reliable.

Other: All in all, a very good deal. Maybe a leather case would be good which can hold the keyboard and the android phone would be handy.

Pros: o Very cheap compared with local prices
o Free planetary wide delivery :-)
o Very good range of at least 5m - how far do you want to be from your phone!
o Works with the Nokia Symbian wireless keyboard .sis file applications.

Cons: o Mini CD ROM arrived cracked and was unreadable (a quick google found multiple manuals including one with multiple languges)
o A paper set of instructions would have been very helpful (especially when the CD ROM is unusable)

Other: o A very nice, cost-effective bluetooth wireless keyboard. Recommended!

Pros: Short list:
+Batterylife
+Rechargeable battery
+Working distance
+Comfort
+Ease of use
+No drivers needed
Explanations:
The biggest pro is its battery life. I've been using it for weeks on just a single charge. I didn't expect it to last so long.
It works on a reasonable distance (+-4 meters), but this also depends on the receiver u use. If you're having trouble with the connection, make sure that there is a clear line of sight between the keyboard and the receiver.
The keyboard feels comfortable in your hand while using it. It is light, and small. Be sure that you don't drop it from the couch because it probably won't survive that.
The keys themselfs feel okay, a soft rubbery finish so they won't feel sticky or nasty quickly.
Tryed it with the following devices with succes:
Archos 32 (Android 2.2.1)- No problems pairing (See other Thoughts)
HTC HD 2 (Windows Mobile 6.5) - No problems at all
Windows XP - Still works without a problem
Windows 7 - And no problems here aswell
The manual is hardly needed. Its all self explainatory.
The male to micro USB cable is included. This makes that the entire package is great value and suited to give as a gift to someone.
Because it has a rechargable battery, you won't have to swap some exotic types of batteries that will cost more than the keyboard itself. Charging is very quick and just 5 minutes is enough for an entire evening.

Cons: Short list:
-Key pressing
-Function indication missing
-Forget to turn it off
Explanations:
The keys need to be pressed pretty far. This makes it difficult to type quickly or make long sentences. It is okay for a text message, but not for use with email or quick chatting or even gaming.
There is no indication when switched between normal keys or function keys. This can be a hassle if you forget what mode it is in.
It's FN + Enter to lock it in Function key mode and FN + Enter again to unlock it (normal keys).
You will forget to turn it off. This is not a major con because of the incredible battery life this thing has. I left it on a couple of nights in a row and it was still working... Must be some new form of energy in there :)

Other: A great value for money.
The battery life is great, far better than I expected. Plastic housing buldges just a little but, nothing to worry about. Works with any device it seems and the charging cable is included aswell as is a driver/manual CD.
A must buy!.

Pros: It does what we expect it to do. It's a wireless keyboard.
I use it in Windows Mobile 6.5. It's very easy to connect.
Very little weight. Key touch is very comfortable.

Cons: Seems that the "Ctrl" and "Alt" keys are not working (at least on my phone). We can't do a Ctrl+C or Ctrl+V to copy and paste text.

Other: Very cheap. I think that it's worth the price I paid for it. I paid almost half the price for only the micro USB wire that comes to charge the battery of the keyboard.

Pros: with the keyboard you can control the music example (play / pause, forward, down and up the volume ...) and when you use the Bluetooth keyboard you can hide the keyboard that takes all the iPod's screen.

Cons: it is not built tough enough it broke in 1 week and the user manual does not explain very well the whole function that the keyboard offers you, i had to find myself. But in general thats not the better bluetooth keybord you can find.

Other: I recommend to buy the sku 57272 it gone tough more longer

Pros: Small (can fit in almost any pocket, it's smaller than my smartphone), seems sturdy, works nicely

Cons: Included "driver" for android is useless Keys are quite small, I wanted to use this keyboard to do some code, but seems like it won't really be comfortable. Even for some chatting. The keys feeling

Other: It can be a great product that you can show off to your friend, but it's not absolutely useful unfortunately.
