1-year limited warranty
Things I liked:It was free..
Things I would have changed:Even though it was free it was worthless. The brass weight did not fit down the barrel.
Things I liked:This is the best investment one can make in a cleaning accessory. Cleans the barrel in seconds and pays for itself in moths by saving hundreds of cleaning pellets and patches.
Things I would have changed:The Copper brush section is a bit long to use in pistols with tight breaches.
What others should know:Will not fit in any Crosman 2240/2300 series pistols
Things I liked:cannot be pulled through,too large in diameter
Things I would have changed:weight is to large where connected to pull through string. also connection where pull through connects to rope too large. will not work in a 177 and too small for a 22
