Question: How long is the cord?
Document: You should probably change the USB cord, though. Clear cabling is so 90s.
Button works great in my photo booth to start session. looks good as well.cons: the cord is a little short.
I like that it came with an "extension cord." The software was easy to configure with my photo booth software (NKRemote Pro). I am glad I purchased this and was able to get it to work. It saved my photo booth AND my laptop as I did not want people to have access to anything but a single button for operation.
Griffin has since updated the PowerMate software to fix this issue, and indeed the problems with presses and turns are fixed, but for me, long press still fails about 75% of the time I try to use it, no matter what settings I try. I know it's not my PowerMate because, like I said, I have two, and they both do it.
Not much more to it. It's heavy, durable, beautiful, and does it's job. Comes with an extension cord if the 2ft-ish cord is too small for you. The bottom of the controller is a clear gum-type of material (think of shoes that have the gum bottoms) that 'sticks' to most surfaces. It is also somewhat clear, and has a blue led that shoots down, creating a glowing blue ring that is really really slick.
Being under impression of few positive reviews about Powermate working as a spinner with MAME Arcade emulator, I have decided to purchase one. How much disappointed I was once I discovered that Powermate does not work with newest MAME32/64 GUI emulator. I have tried to contact Griffin support, but despite of several emails received with long delay they were unable to help.
I bought this to use as a button for a DIY photo booth I was making. It worked great and looked great. I have since used it for other purposes like editing in adobe premier using it to scrub through the time line and the cut. I also use it when reading manga online having set the rotate to scrolling and the press to click right.One problem it that the usb cord is short so you may want a usb extender.
First, the cord is way too short. It's maybe 1.5 to 2 feet, and that's just not enough unless you have a USB hub built into your keyboard.I wish there was more competition in this product category. I certainly looked hard for alternatives before buying this but couldn't really find anything comparable in price and functionality.I'm not really satisfied with my purchase. The software that you can download to configure the device (assign sensitivity, actions, light behavior) is inadequate.
In any case, I was surprised that such a Mac-friendly company took so long to offer support for the latest OS. I hope they do better going forward.Some of you may also be interested to know that Griffin has announced a Bluetooth version of PowerMate that should ship later in 2014. I wish this was around before I bought mine because I had to figure out a way to get USB into the next room for my project!
I really do not know why I purchased this. It's fun to play with and serves as a glorified volume knob. I setup a apple script to put the computer to sleep on a long hold. It does add some nice desk appeal with the blue glow and brushed stainless look. It also has some nice weight to it and does not feel cheap. My only suggestion would have bee to make the cable flat so that it could be placed underneath a monitor stand.
Answer: 20 inches plus an included 43 inch extension.
