Read a few gun magazine reviews for them...even those guys (who absolutely love any crappy product as long as the manufacturer keeps buying advertising space) were unimpressed with the accuracy.
"While the 6-inch groups our test gun produced could have been tighter, in reality they were perfectly adequate for 99% of the shots taken while Marco Polo sheep hunting. They, and the test gun's 15-lb trigger pull, were more than offset by the cool good looks and nice loud "bang" almost every time we pulled the trigger."
Seriously, accuracy in three tests that I've read has been mediocre at best, and disassembly for cleaning is apparently awkward. Strictly word of mouth, I have only fondled one in the local shop. Hopefully you can find someone with first hand shooting experience with one.
