  • The shooting is really good and accurate; 99% of the shots are identical—the rest just depends on the weapon.
  • They are all identical and none of them are deformed
  • It's made of really good material and is high quality—it's not flimsy, so you can't just crush or bend it that easily

I also shoot a .22 rifle and a hunting rifle and I was thrilled by how accurate an air rifle can be even with, let’s say, basic ammo. A 12 mm spread at 45 m really isn’t a problem.

  • Accuracy!!!

  • Proven quality and also an acceptable price.
  • The packaging of these "Devils" could be of higher quality (e.g., plastic boxes with a screw cap).
