I don't have the spring loaded version. I just received the version Kustom King sells and gave it a try yesterday.
There is a bit of a learning curve if you're used to the Little Chopper. On the Bearpaw, the side that holds the feather is the 'lid' so to speak and the feather goes in upside down with respect to the way the Little Chopper loads/functions.
The foam runners that grab the quill work well, but this part gets chewed up pretty quick.
The cutting blade itself sits in a plastic piece that is held in the base by a couple of screws through a plastic tab on either side. I got through about 4 feathers when one of the tabs broke. I was using a rubber mallet and had the cutter on a fairly firm surface. Didn't feel to me like I overdid that particular whack, but who knows?
Even with one tab broken, it'll still work properly. The replacement blades are fairly inexpensive so I may just order one and try it again.
