I haven't found many online reviews anywhere regarding this specific racquet. After purchasing it, I can say that it is definitely worth the price and I feel like the Duora 99 is getting slept on (meaning you can't find many people talking about it in general). It stacks up well and is more affordable compared to other high-end racquets, especially in the Duora line. I found it good for smashing, yet it's still maneuverable enough to defend against quick-oncoming attacks (most likely thanks to the Dual Optimum System).
Also, I wanted to say that the shipping and product quality was excellent. It came in fast and had no damage. I say this as other badminton shops I purchased from typically give me damaged racquets (paint, scuffed, etc.), so I was very pleased to see that Sports Virtuoso has quality at the top of their checklist.
