The Premier Spike set is definitely the highest quality out there! I got this set when I had a Spikeball set rim break, and I had played on a Premier Spike set in a previous tournament. I didn't want to buy another set that would easily break, and I also don't want to put unnecessary plastic in the landfill by continuously buying replacement parts. So far, this set has not disappointed, and I especially love the design of how the rims snap together!
I've been playing Roundnet for about half a year, and I absolutely love the game and I think the Premier Spike set does an excellent job of eliminating debates over fair plays. That's to say, it's much clearer to hear when the ball hits the rim versus when it's just a roll-up, and since the tension on the net is consistent throughout, pockets will make less of an impact during play.
The included serving line is really nice, and when playing in hard surfaces the legs which double as ball-holders are a lifesaver. I personally enjoy playing with the legs faced inwards so they don't interfere during play (my friends and I usually don't stress about the no hit zone), but the ability to turn them outwards makes it really nice if you're practicing by yourself.
The only thing that I feel hesitant about this is the Premier Spike balls. I would 100% still recommend purchasing this set, but try out the balls with the two that are included with the set before you purchase a lot. If you're used to the Spikeball Pro balls like myself, it's definitely an adjustment. The size of the balls is really nice, and while I know some people complain about them feeling slippery, I haven't found that to be the case. The main thing that bothers me about the balls is that their texture seems much harder. After practicing setting with the Premier Spike balls, I have found my hands tend to sting a bit. If the balls' surface was slightly more rubbery, I think this problem might be eliminated.
Wonderful product, Premier Spike team, keep it up!
