What is Reddit's opinion of Spalding NBA Zi/O Excel Basketball?

From 3.5 billion Reddit comments

Get this one mate. I've tried a lot over the years and these are the most durable.

I play primarily on coarse concrete courts cause that's all that's around here and these last a fair amount of time and are a lot cheaper from amazon than to buy in Aus by something like $30. Obviously the kind of concrete or cement you play on will determine how long it'll last, no rubber/synthetic leather will ever last long just cause it so harsh to play on.

Don't buy this version IN Aus stores though. For some reason they have the same name but are made differently and are shithouse but they sure as shit price them up.
