Review on Kevenz Advanced Orange Ping Pong Balls - 60 Pack For Outdoor Fun And Games by Zachary Pete

I bought 3 of these 50-ball packs. I ordered the 40+ version, which is the new regulation size (slightly bigger than the old 40mm balls). At about $10 per pack, this is the best deal for 40+ training balls. I bought these to use with ipong robot. They work great. Even though they are not ITTF-approved balls (meaning you can't use them for tournament events), they are of great quality. Solid bounce and plenty of spin.Out of curiosity, I did some bounce tests against several different brands of ITTF-approved tournament grade balls. The result is really good. KEVENZ 40+ balls, for the most part, is on par with tournament grade 3-star balls (DHS D40+, Xiom 40+ seamless, Nittaku 40+ Premium, Xushaofa 40+ seamless).The only thing I'm not sure is whether KEVENZ 40+ balls are actually 40+ size. Since it's not ITTF-approved, they could just stamp 40+ on 40mm balls. Most people won't be able to tell the difference, unless they have precision measuring tools. But I'm not too worried, because I only use them for training; and for that purpose, they work wonderfully.
