Review of ASG Dan Wesson CO2 revolver

Hi.
On a whim last Xmas, I bought the ASG/Dan Wesson CO2 revolver in 2.5 and 6 inch models.
I also bought the 715 model in 4 inch. All are .177 pellet versions.
The 2.5. broke almost immediately (cylinder rotates freely in BOTH directions, but I still can cock the hammer).]
Tried to find parts, but no luck. I also noticed a definite difference in the build quality of the 715 replica version as opposed to the standard CO2 version.
Called Amazon and they refunded my money with no questions asked and told me to keep the guns since returns were not being accepted.
Good customer service! Now if I can only find a way to fix that 2.5 in, that's broken!
