Things I liked:Easily set up for backyard, or indoor target shooting. Would not recommend for velocities above 500fps, as you will shorten the useful life of this trap, but performs great with most .177 air pistols. Things I would have changed:Increase the strength of the deflector in the back of the cone. Assembly, although not difficult, the instructions could be more precise. What others should know:Make certain to ONLY HAND TIGHTEN any and all screws until the trap is assembled. It will all fall correctly into place, and at this point fully tighten all screws. Must admit, I learned this the hard way. People with 1377's, a couple or three pumps are sufficient for target shooting. For you air rifle shooters, get a trap that is better constructed. You'll easily destroy this one within a short period of time due to too much muzzle velocity. Another lesson learned the hard way.
