Do NOT buy for iMac Bluetooth Keyboard
929085
This does not fit the iMac Bluetooth keyboard. The key bubbles are too shallow and the length is too short - the protector hovers over the keys instead of fitting onto them. It's like typing through bubble wrap. I have to press twice as hard on the keys and the entire piece shifts all over the place when I touch it. Guess I'll just use it to cover the keyboard when I'm not using it.

I bought this in order to use an Apple keyboard with a lightning plug ( see photo) with my late 2009 iMac which requires a USB plug.

Sadly, the Mac didn't recognize the keyboard.
Perhaps this was the wrong choice for this application.
I'm sure this is a great product. I may simply have wanted it to do something for which it was not meant to do.

The only reason it got one star is because I couldn't give zero.

I have a new Mac OS X 10.7, and I wanted a keypad to go with it. I got one of these, and the computer could not identify it as bluetooth capable. I tried it with my older Mac, and that didn't work either. So, after about an hour with tech support, I sent it back to Apple (from whom I ordered it; sorry, Amazon!) and they sent me a replacement. That one didn't work either!

Apple would do well to disassociate itself as much as possible with this product. This product is the opposite of everything that makes Mac products what they are: it's ugly, it doesn't perform as it ought to, it's a little plastic piece of inconvenience. I cannot stress enough what a magnificent disappointment this product is.

It has potential to be an excellent keyboard; i got it because I dontt like the new Mac keyboards, so went for a big iPad with this.
the first problem appears to be an intermittant disconnect; it randomly won't accept text in certain apps. Havent been able to pin it down, but possibly a BT conflict with the Apple pencil.

The space bar doesnt work properly if you tap it on the right-hand side, which is very irritating. I stopped using it after a couple of weeks so it is a very expensive paperweight now.

Bluetooth version will not connect. I have been trying to get it to connect to my raspberry pi 3 for awhile now and it will still not connect. I do not recommend this "Bluetooth" mini keyboard. Do not buy!

Don't buy this keyboard.  I connected this to my windows laptop and it worked for about 5 minutes then stopped.  If I reboot the laptop it will work again for a very short time.  I have had the same problem with this from the minute it arrived.  I contacted the manufacturer for support and they asked me to pair it to my iPhone to test.  It exhibits the exact same symptoms paired to the phone.  Still they did nothing to help and I am stuck with a non functional keyboard.  Not worth the money or hassle.

It doesn't work properly with my Mac, even though it claims to. And Logitech customer service has been useless

Tablet bluetooth did not function at all with Windows 10 installed with Bootcamp on iMac.  I returned item and would have probably kept it except the the two free software programs from Corel would not let me activate them which basically put the software in trial mode and set to expire in 30 days.  After contacting Corel support, I realized that they were not going to help with the problem.  This problem added to the bluetooth problem left me no choice except return.  I figured the fact that the tablet did connect to my iMac was worth two stars.  Minus stars for Corel software.

The first keyboard I bought (brand new in box) did not work. The local Apple store refused to get involved because it was a third party purchase. I returned it to the seller, who replaced it. I used it for about a year and it began malfunctioning. Screen popup says this is a non-supported accessory. On close inspection it appears the middle button of three on the keyboard has receded so it no longer touches the contacts on the ipad. Tried prying it up, but it does not budge. Before you consider this, go into the Apple forums and review the comments from people who are having the same problem. This design is clever, I will give it that, but at the price of this keyboard I have to conclude it is poorly manufactured. As many people have mentioned, the lack of back lighting on the keys is a major drawback. The keyboard is awkward to use in your lap.. This expensive device has become a very expensive ipad cover.

If you're looking to use this to add bluetooth to an old mac, or a hackintosh, do not waste your time. Maybe it works great on Windows, but claiming Mac support for this is simply not realistic. For WiFi you have a chance...

I've owned my Apple keyboard for about 2-3 years. Suddenly two of the keys stopped working.  What a bad deal!

UPDATED REVIEW - My original review is below. After I shared it, the manufacturer reached out suggesting the unit I had received was defective and sent me a replacement. I am physically able to see the keys more uniformly raised on the replacement, and I appreciated the actions of the manufacturer. However, I stand by my original review - this keyboard is not sufficient for someone who types regularly for two reasons:

- It constantly loses connectivity after a minute or less, requiring the user to wait again and again for reconnection.
- The keys are not well-designed. Sometimes they don't react, and sometimes they get caught on the keyboard frame depending on the angle at which you strike them. This issue is highly restrictive for quick typists. Apple keyboard keys will depress regardless of the angle at which they are hit.

To summarize, this keyboard is poorly designed and works poorly. In order to maintain a high typing speed, I have decided to purchase a better, more expensive alternative from a competitor.

ORIGINAL REVIEW - After buying this and using it for a few weeks, I think I should have bought the Apple bluetooth keyboard instead. Apple products are crazy expensive and that's why I went for this cheaper product. I wanted a keyboard which had "flat" buttons and bluetooth capability so I didn't have to worry about cables or even a USB receiver. There are two problems. First of all, the keys are not as responsive or springy as Apple keys, which I've grown accustomed to. It's almost like certain keys require extra effort. Secondly, the keyboard constantly disconnects and takes a few seconds to reconnect. As an internet user who watches videos frequently, it's annoying to have to wait 5 to 10 seconds for my keyboard to reconnect after each video.

I bought this keyboard for one primary reason. It's to use on my (mid 2009) iMac. This product did not work at all. My iMac was able to see the keyboard via bluetooth, but when asked to type in a numeric key code to fully connect the device, they keys did not work at all. I've tried restarting my computer, turning the keyboard off and back on, but this keyboard just isn't compatible. I guess you can't expect much from a $13 knock off. I've ended up just spending the $60 on an apple keyboard. I should have done that the first time around instead of trying to save money.

As far as build of this product, it honestly seem fine for the price. I just wish it worked as it was advertised. Buyers be cautious with this product because it just might waste your time sending this back to amazon after a mere 15 mins to trial and error.
