Wacom ACK-40401-N Wireless Accessory Kit - Black

I bought this to use with a  Intuos5 Pen and Touch Medium Graphics Tablet , and it does exactly what it's supposed to. The kit is three separate small modules: the (tiny) USB wireless receiver you plug into your PC or Mac, the wireless module you plug into your tablet, and the battery for the tablet. The Intuos tablet has one (for the Small size) or two (Medium and Large) doors on the bottom that can be removed, to allow inserting the wireless module and battery. Installation takes a few seconds.Once inserted, it's recommend that you fully charge the battery via the USB cable connection before using it. You're free to switch between wired and wireless operation at any time, and never need to remove the wireless kit to do so. When you're ready to go wireless, just unplug the USB cable, and press the power button on the side of the tablet (the power button is part of the wireless module, so you'll only have one if you've installed the kit).Since this is just a USB wireless connection, there's no software to install. In terms of battery life, in Standard mode (the default mode for Intuos tablets), you'll comfortably get two or maybe three days of periodic use from it, and even with heavy use shouldn't need to charge it more than once a day. There's a battery gauge shown in the menubar on OS X, and presumably somewhere similar on Windows. There's no difference in performance (no lag or jitter, particularly) between wired and wireless mode.Basically, it does exactly what it's supposed to, with no fuss. Highly recommended.

Whilst occasionally I have some trouble getting the wireless to connect, when it does it works very well and so far I haven't had to recharge it since originally getting it and charging it over a month ago, which is great! I only use it for short periods at a time though, so that may be why.It was incredibly easy to put together and set up - though as others have said, I do recommend giving it a full initial charge before using it for the first time, as that really does then seem to last.I find the communication between the tablet and my PC to be very good and without much lag and due to the way my PC is set up in my bedroom, using my tablet via its' very short USB wire is out of the question and I feel this accessory kit solves that problem very satisfactorily - not to mention it is a lot tidier than having wires everywhere, even on a regular desktop set-up.

The first thing you notice about this kit is how small it is. I ordered this along with my Bamboo Fun Medium Graphics Tablet, which arrived at the same time in a box BIGGER than I had expected, so the difference in size between the two was almost comical. I set up the tablet with its cable first of all, and it's certainly true (as has been stated in almost every review of the product) that its USB cable is far too short. I have no space for the tablet on my desk, so it sits on my lap, which I feel is the best way to use it - this wireless kit allows me to do that very easily.As I say, the kit is very small, and you do feel that you may have paid a bit much for the three small black items (battery, two wireless units) contained within. However, the wireless kit is still incredibly useful indeed and adds a certain sense of freedom to the use of your tablet that just cannot be achieved with it hooked up to your computer. It feels far more like a device in its own right (especially as the wireless kit adds a power button) and not just a glorified mouse.All in all, a truly handy little kit - if only it were a bit cheaper!

I have three problems with this kit:1. It requires using up a USB port for the Wacom "dongle". Why they didn't use Bluetooth is beyond me. I have a bluetooth keyboard and mouse, both of which have worked faultlessly for years.2. The power button for the wireless accessory kit is really badly designed. It is slightly recessed, so when you pick up the tablet you have to fumble about to find the button, which is actually quite hard to press. I have fixed this by gluing a little bit of plastic on the button so that I can easily find and press the power button by touch.3. The first two issues wouldn't be so bad if the wireless signal was reliable - it is not. Sometimes the table connects ok, but more often than not it fails to connect, or disconnects randomly after a few seconds. It's next to useless. I want to be able to pick up the tablet, hit the power button (see point 2) and go. It just doesn't work this way. After much frustration, I've given up and gone back to the cable. I'm running OS X 10.10.3 with the latest Wacom drivers, which I updated recently and it made no difference.Update: I stand by the first two issues. However it turns out the connection problems were due to low battery. The Wacom software was mis-reporting the battery charge - it was reported as 75% even though it must have been very low, causing the connection to drop constantly. Re-charging to 100% has fixed this and connection is now reliable. I will be re-charging the tablet more regularly in future and ignoring the charge level reported by the software.
