Absolutely love this product. Brilliant design and perfect for training and coaches. Nothing is worse than having a ball knock over a cone and having to jog to the other end of the pitch to fix it...stupid grip less cones.
The biggest drawback to going wireless is the stupid batteries, they always seem to die when you have no extras around. This pretty much eliminates that issue all together. No wires, no replaceable batteries, pure awesomeness.
We have all used those cans to get rid of the debris from the keyboard but this is soooo much better. make your keyboard look like new instantly with just some water, also get rid of those non-digital sticky keys.
Now when you get that million dollar idea during your shower you can write it down and it won't just wash away! Honestly though a lot of good ideas have come to us in the shower, like circular hot dogs.
Just about the most science fiction thing we have seen. You can now create a keyboard on any surface. it uses light sensors to determine which key you are pressing and is compatible with all devices that allow keyboards.
