I have had this pool for two years mm ow and it has been great. The setup is is fairly simple, but requires at least 2-3 people to attach the metal bars together while maintaining the upright position. It requires a lot of pulling as it is a very sturdy pool. I cannot say enough about the sturdiness of this pool . Of course, as with any pool it has to be on level ground. The liner is thick and we have had no problems with holes or tearing. The pump is quite simple to install for one person. During operation it is definitely best to keep the manual handy to read the codes on the pump. The ladder is why I rated this a 9. The codes on the pump are very helpful with troubleshooting the pump and maintenance of the water . In my opinion, I think it could stand to be a bit more sturdy. It moves quite easily in the water and seems a little unsteady. All in all, I am very happy with this pool!
