testing ergonomic keyboard

I'm presently testing a Periduo-606 Ergonomic Keyboard. I had trouble finding a double A battery for the mouse so I'm just using the onboard mouse of my Macbook Pro for now. It's made by Perixx I guess and my daughter found it online for me. It arrived today likely from Amazon in 1 or 2 days so really quick. I'm finding it a little hard to get used to because it is quite different than a normal keyboard but supposed to help prevent carpel tunnel while typing. It takes 2 triple A batteries and if you get one remember the USB fitting to make the thing work is inside the mouse next to where you put the double AA battery. I'm using it without the mouse right now because I haven't found the double AA batteries in the battery drawer yet.
