a 'killer" coin sniper! i have the 12 and the 8 and 'both" work equally well. it's a battery drainer for sure.they just developed a lithium-ion battery pack for it fits seamlessly in to the control housing gets 30 hours i understand.i ordered one
another thing is the build quality!. it is very good, they use 'tough" plastics, and i don't anticipate any issues with it over time...excellent value for "short money!"
