Solid construction, would purchase again if looking for stationary dummies as obstacles. My 8/10 yr olds have tried to use them as a "wall" blocking free kicks and the dummies fall over when hit with a strong shot. I would recommend ones with springs specifically for that use vs the rigid construction ones. If not being used to prevent shots, the spikes do hold the dummies solidly in grass/dirt. Easy to stick into the ground. Have left them outside often and they look good as new. 4 foot tall or so.
