I've not seen that specific device, but I've seen contraptions similar before. They work good if your hands aren't strong enough to do it barehanded or if you're doing a million. I prefer to use my hands because I feel it keeps the animal calmer than being inserted into a device like that.
Rabbits are a little calmer of demeanor than quail and it didn't seem to bother that bunny too much, but a quail would be losing it in your hand unless you're doing it at lightning speed.
Honestly if you can't do it quickly and humanely in your hands or with scissors you won't be able to do it much better in a device. It's more about mindset than difficulty. As far as easier maybe the bar makes it physically easier but it won't make it any faster, it already takes less than 2 minutes for me to process a bird. I made a couple of videos on processing quickly and humanely, the links are in my signature.
