I've only had this device for a few days but It's working great.
I was torn between the GTRS V-Boy and the Cylon. I finally settled on the Cylon. There are several reasons why. One was the placement of the fire button. I'm not a fan of where the fire button is on the V-Boy. The price was close but the Cylon was a little cheaper. I also like the ease of using the menus with the Cylon. Most important and what finally settled it for me was the fact the Cylon has both batteries showing on the screen in real time and the V-Boy didn't.
This is a very good device and I highly Recommend it!!
