We got this new tetherball system to upgrade/replace our old one and we love it! Our old system was just a pole in the ground in the middle of our backyard. The best thing about this new system is the portability! We were able to use it in our backyard and then immediately move it to the front yard to include neighbor kids! The stabilizer kit is great. It stayed upright and stable whether it was a kid or adult playing. We filled the base with water, but plan to replace it with sand before the winter hits to avoid any freezing concerns. Assembly instructions were a bit confusing, especially when installing the split collar, but we figured it out and it was smooth sailing from there. We love having this new system and highly recommend it to anyone considering it!
