Things I liked:Not expensive, relatively well built. Things I would have changed:The back of the trap is too narrow: When used with 5-bull air rifle targets and shooting the bullseyes on the corners, the trap shakes side wise. Nothing serious, but still a concentration killer and it doesn't help for the follow-through.
Spot-welding a flat steel plate and providing two or even four mounting holes would really improve this product. At home, you can still try epoxying it to a piece of plywood or something similar.
Things I liked:Great shape with reinforced skirt base, clean, uniform and fairly accurate (although less accurate than the unfortunately-discontinued Club 10) in my SAM M10.
Great value for the money. What others should know:They look exactly alike the now-discontinued RWS Club 10 pellets, but don't shoot equally well. I have tested shooting several 10-pellets groups with my SAM M10 clamped in a vise and at 10m the groups are a good 10-15% larger. It is also true that the Club 10 shot practically the same as the R10 at a fraction of the cost. If I'm in good shape I don't think I'd use them in any competition, although I already managed to get (barely) a 5-shots perfect target with these pellets.
