Hi all, Just got the Ax77 4u4 one month back and I'm absolutely enjoying the change in my game with more power and steeper drops and smashes. I have the Yellow color 4u4 version strung with NBG 95 25 mains 27 crosses. With AC102EX black grip. Testing it for the first time: It felt really weird cuz I've been using a really old and not-so-good racket (Voltric ld 100) and using an Astrox racket for the first time felt weird. Clears required more effort and the sound just fell different. However, I noticed more power immediately. After 1 month of constant use for 2 hours a day: Love it, way way way better than my older racket. As I'm an intermediate singles player, this suited me the most. I never use it for doubles (As I don't want the racket to end up cracked ). Overall, worth the price, definitely feel the steeper smashes and bigger sweetspot. My Thoughts: Go for it, if you want an upgrade from a racket you don't like. For who is it: For more attacking kind of gamestyle or neutral in singles and suitable for all round in doubles. Just suitable for anyone. After almost 1000 hours of use: The Astrox 77 feels nothing like what it felt when I 1st tried it. At first it felt hard to generate power and felt weird, but now it feels like a hot knife through butter, can easily cut through the air (4u version) and plenty of power available. All round racket and no specialty other than being conservative and good at anything, no weakness about the racket. It also helps you get out of trouble in deep positions in the court with ease as its not too head heavy or demanding to use. Just a suggestion, for those who think the nbg95 is a wet noodle and not plenty of power available, try the nbg99, more bite and more power in it, durability is noticeably less in the 99 compared to the 95 but still very good. My ratings for the racket and final thoughts, is it the perfect choice for you. -So the Ax77 was the 1st astrox racket released by Yonex. Even though its the first one, its really nice to use, no visible defects with the racket, plenty of power and plenty of speed and quick movements. Definitely meant for intermediate to advanced players IMO due to the medium flex shaft. The good thing about this racket is that you can get out of bad positions in the court with ease as its not a very demanding racket to play with neither is it oo head heavy. My ratings -Speed: 9/10 -Control: 9/10 -Power: 8/10 -Playability - 10/10 -Stiffness - 7/10 -Head heaviness - 7.5/10 -User-friendliness - 10/10 -Overall performance - 9.5/10 I really recommend this racket to a person who is looking for a racket with power but also with a pretty fast frame. If you are already using the current flagships of astrox like the 88dp or the 99p to the 100zz, this might not be a choice unless you like the feel of this but if you are transiting from a head light or lighter racket to a more head heavy one, this is your perfect choice.
