Rating: 3/5 Good...but... October 17, 2019 ...now that Apple's come out with their rechargeable wireless keyboard including a number pad, I stowed this device.

I found it lost its Bluetooth connection just enough to be irritating, and resetting wasn't exactly the most intuitive thing in the world.

Having said that - while I used it, I was grateful I had it, and the build quality was good - though not comparable to Apple's.

Rating: 4/5 Works great! July 22, 2013 Great number pad! Took just a minute from the box to using it. Nothing needed to install or configure. It even matches my Macbook Pro. There are only 2 things I would like to see improved on it: The keys are not illuminated like my laptop and there are only up and down arrow keys but not the left and right. Otherwise, I would give it a 5 star.

I would recommend this item to a friend!

Rating: 5/5 Works as it should! July 3, 2013 I've had this for over a year now and I can't work without it. If you're looking for a keypad and don't want the full wired Apple keyboard, this is for you. Laying on the desk, it's a pretty close match to the Apple Wireless keyboard (color wise). It's made of plastic, hence the price. But because it's such a close match it really doesn't look like it is.

I will say that the initial connection setup can be a little tricky but once you get it connected and set it as a favorite device, it connects and stays connected just about every time. I've had instances where it lost connection and I had to setup the bluetooth again, but it doesn't happen enough for me to get frustrated.

I love that it's wireless and it's worked without complaining for over a year!

Rating: 2/5 Worked OK - then died shortly after warranty expired May 9, 2013 I quite liked this unit when I got it. I had some issues with how long it would take to 'wake' and connect to my Mac if I hadn't been using it shortly before, but it always did. Apart from the numeric keypad, it has been great to be able to have a 'Del' key for logging on to some Windows VMs on my Mac. However, a few months now after expiry of the warranty, it has completely stopped working. New batteries won't help - it just wont light up and try and pair when you press the button in the back. Sigh. If it is this flakey, I won't be buying another to replace it. I should be able to expect a fair service life from a unit like this that has never been moved from my desk - and and 15 months is not that!

Rating: 5/5 Works great for me March 6, 2012 I honestly don't understand the negative reviews of this product. I'll admit I'm not a HEAVY user of the keypad but when I need it it just works. Tap a key it wakes up and stays that way. I don't have the sleeping, pairing or stuttering issues mentioned in the negative reviews. I think this keypad is great and considering the price I'm very happy with it. I highly recommend it.

Rating: 4/5 Love this product January 11, 2012 Is this keypad perfect? Of course not, no product (not even apple's own products) are perfect. There are some occasional connection issues but I can't really blame the manufacturer. I have the standard Apple bluetooth keyboard and the magic trackpad - both lose connection more often than the keypad. The biggest issue I have with the keypad is the pairing but I don't think it is entirely the manufacturer's fault either. Sometimes the keypad will disconnect and the OS still says it is connected. This happens even if I take the batteries out so it can't be the keypad's issue.

Oh, to the review that said this is a fail because it is plastic... Seriously? The color matching is pretty spot on so who really cares? It is the best we have. Apple doesn't make one themselves and if they did it would cost a lot more than $40.

Rating: 1/5 Doesn't work July 20, 2011 I'm on my second one of these things because I really, really wanted it to work. I still try to use it, but I'm about to give up.

It won't stay connected. Every time I use it I have to wait 20 seconds or so for the bluetooth to reconnect. Nevermind that it's crummy plastic.

Response from OWC, Technical Support January 4, 2012 OWC has shipped thousands upon thousands of this item to very satisfied customers and Apple even now offers this in their own stores. Cropmark has improved both the directions and the pairing explanation since the this product began shipping in 2010 - to address a misunderstanding with how this worked that was reponsible for complaints such as yours.

Rating: 1/5 Waste of time June 26, 2011 Great idea, nice design, complete failure from a user standpoint.

The idea is great since Apple doesn't currently offer an extended bluetooth keyboard. I've looked at several from other vendors and they are just too big for the space I have for my keyboard/trackball. The unit matches and connects to the aluminum keyboard nicely and looks good. Then the trouble starts.

The keypad is constantly going to sleep which gives you the "connection lost" notice and the "connected" notice when it wakes up. Of course, the keyboard assistant wants to identify the keyboard each time so you are constantly having to close that window. The keypad also has a tendency to lag so you aren't always sure if the keystroke will show up and sometimes stutters and inserts the number multiple times even if you only hit the key once and are not even making contact with the keypad.

The docs indicate these problem can be caused by low power. So every time the problem gets to bad to ignore I change the batteries. In 10 days I have changed the batteries 4 times. I used the alkalines that came with the board and 3 sets of freshly charge NiMHs. I checked the NiMH and the are showing good on my charger, they are less than a year old, and they are the LSD type. The same batteries last a couple of months in the Apple keyboard. The keyboard and keypad are located less than 3 feet from my Mac MIni and there are no significant obstructions or objects to block the signal.

So, either I have a unit that is bad out of the box, which bring their QC in to question, or the design is inherently flawed.

Rating: 4/5 Something desperately needed May 16, 2011 So, I am a recent Mac convert. I have been working with MS since DOS days and couldn't wait for the Mac to become more mainstream. The day finally came and I bought an iMac. Imagine my surprise to find that the wireless keyboard has no keypad. I use that religiously and found it very hard to break that habit. I was reading an issue of Macworld and found this product in a review and bought it without hesitation. Next to buying the actual Mac, this was the best purchase I have made. It matches perfectly and works flawlessly. There are only two issues I have. The first is that I would have liked it to be aluminum like the actual keyboard. The second, and really more important, is that in VMware Fusion, the keypad is not recognized - making it unusable in my Windows environment. I have two applications that I have to use Windows for - and one is number intensive. I hope there is a way around this, and will be looking for an answer (I've only had a short time to use the product so far). Other than that, I highly recommend this!

Rating: 1/5 Poor performing product May 15, 2011 In my setup (a Mac mini attached to my HDTV about 8 feet away from my keyboard), this keypad would not stay connected. It would constantly drop the bluetooth connection and sometimes would reconnect within a few seconds of pressing a key, but more often needed to be repaired with the computer. Troubleshooting suggested that batteries might be low, but I am using brand new, fresh Duracell Ultra batteries. This unit seems to work best with line of sight, but even then, it would randomly drop or worse, mindlessly repeat keys as if I was holding down a key. My advice for this unit is to either find a previous Apple wireless keyboard WITH the numeric keypad or live without the Apple keypad on the aluminum wireless model. Doing without is really a better option than using this thing!

Rating: 1/5 awful March 17, 2011 The tech at OWC said they are hearing lots if complaints about this keypad. It is difficult to pair and once paired it turns itself off every couple of minutes. If you don't want to spend most of your computer time trying to get this thing to work, don't buy it.

Response from OWC, Executive December 27, 2011 It is unfortuante and not accurate that an OWC tech suggested there were 'many complaints' about this product.

Rating: 5/5 LMP Bluetooth Keypad February 24, 2011 This keypad is great. I never enjoyed using the bluetooth keyboard at all because I hated having to use the numbers along the top. I ordered this Keypad the same day I saw it advertised in the MacLife mag. It fits perfectly along side the keyboad and fits snugly. The keypad itself works flawlessly. I have not had one bit of trouble with it what soever. It works just like it is supposed to. This to me makes using my bluetooth keyboard feel like a wired keyboard. The best money that you will spend. Thanks OWC for carrying this product.
