4.0 out of 5 stars okay set okay set overall, could be better for its price tag.The jump ring is a joke, it is just a cheap plastic flex tube that doesn’t have anything to connect it together at all and will easily be punctured by claws or teeth.. You use the velcro to tie it to the pole as shown in listing pic but, that does not stop the tube from slipping out as soon as your dog jumps through the tube ring.. Definitely NOT good!!The poles are all not bad, go into ground deep enough to not be knocked down when a large dog goes throw obstacle course however, the jumping across bar doesn’t stay in connecting pieces well enough, as soon as my dog goes under it and brushes on that bar, it falls out of connecting pieces. As soon as he jumps or walks over the bar, it falls down.. Hub says it is suppose to be like that (fall out easily) so dogs don’t get hurt if they miss jumping high enough but, i don’t know about that. personally not into having to reattach the bar every time while he is training..the tunnel is large enough for our 80ish lb GSD boy, at least large enough for him to semi squat as he runs through it.. good size and so far holding up well and inside wires on outside ends isn’t popping out/ripping through yet…overall okay set, not so sure it is worthy of the eighty price tag though..
