Finally! Something that actually plays more like a celluloid ball. I tested it with Dan and Tom when they reviewed it and have used it a few times since. None have broken so far and all seem to be quite round. Bit of a weird surface which you have to see first hand to understand. It's also a bit glossier then other plastic balls and looks almost rough but doesn't feel rough. I really don't like the plastic ball when I'm comparing it to the old celluloid due to its heaviness and lack off spin. The g40+ feels lighter (some might say feels too light) I don't see this as an issue as you get used to it and would say all other plastic balls are too heavy. The speed however is its main asset it's quite a lot faster then all other plastic balls I have used and I've tried most of them. Butterfly (not g40) stag, nittaku, XFA to name a few. I feel it puts more fun into table tennis again. Which I found the other plastic balls took away after the celluloid ban. As for spin it's the same as other plastic balls and still not really very near the old celluloid balls but you can't have everything eh...Some people will complain that's it's too different to other plastic balls. Which I agree to to an extent as it is very different. However I think it's much better and it won't be long before this ball takes over when people realise how good it is.
