Friendship/729 Aurora Max PRO

I have the medium-hard sponge. Decent all around backhand rubber. Not too slow, but not fast for sure. Unboosted it feels quite unremarkable, and feels a bit like a beginners rubber. Speed would be like a 8.3 or something. However, after testing a little Haifu Seamoon on this rubber, it reacts incredibly well. The bounce becomes more than MXP or Tenergy or other popular bouncy rubbers. It literally is the bounciest and fastest rubber I have ever tried. Speed is 9.5 with booster. Its quite spinny as well. This rubber is very fun to power-drive with on the backhand, and very fun to block with. It feels like it has a lot of control with a lot of rebound. Booster is a must on this rubber. Don't recommend this rubber if you don't plan on boosting.

Updated Sep 14: What Aurora, just rename it as "Sad throw away" rubber (worst rubber I have reviewed), I would be happier getting a Happy Meal instead. This sad rubber is not tacky or grippy for proper backhand power loop (Yinhe Moon Pro (M) and Moon 12 Blue (H-) are much better). EJ virus and positive reviews led me to Aurora Max Pro Red Semi-Hard (uncut:68.5g (heavy for backhand) cut to 48g on 158x150 Nittaku Factive Carbon; the 3.6 rating here is a joke, App owner might want to change this to float rather than ordinal metric that is not giving any useful weight info).

Good rubber for improving BH technique. Medium hard topsheet and a soft sponge. Nice spin with good technique. You shouldn't buy it for FH because it has not enough spin and it is not so speedy for FH. Better buy AK47 Red if you like cheap tensors. Throw angle is enough high for a Chinese rubber. 9 month and this rubber is like a new! Wanna change it only because I think I improved my technique. I think this one can survive for 2-3 years

A very cheap rubber with decent speed. It is much more linear than many tensor giving it extra control. With pro points out of the way, let's get to the cons: When you remove it from the sealed package and the foil, the rubber forms a O shape with oposite edges touching. This makes glueing and cutting impossible. I've been able to glue and re-glue this rubber only heavily boosting it to reverse the O effect. Even then you have to take care, too much boost and it will bubble up. If you don't boost, the O shape effect is so strong it will come off your blade eventually. Rubber is nice and solid, orange-reddish looks durable. The topsheet is the problem. Slightly tacky it will stain and look bad imediately after a few balls. It also smells and looks like cheap tire rubber, durability of topsheet is poor. All in all is not worth it, but is a good step in the right direction, maybe next version without factory tunning it and with a better top sheet.

[Update after booster] still not good, won't buy this again. First of all this is a cheap rubber, I have the medium soft and uses it as my bh. I was using Tibhar Auros soft before trying this one, and I think this is much worse than Auros soft. You can't even trust your back-end with this rubber. When you do slice, the ball goes too much, and makes it very easy for your opponent to open. When you want to block the ball, you fell the rubber can't control the ball, and cannot go to where you want it to be. So for this, I don't even recommand, you may try when you are just a beginner for a very low price. I will try to booster this rubber and see if it improves.
