Comments: I have played 6 times so far with this racquet and I'm very pleased so far -- good plow through, good on underspin shots, and good on my serve. I don't use much topspin and this is very good on low deep flat returns. Very good at the net. It weighs 12.5 oz now as I replaced the grip with a gel grip and a Yonex overgrip and I also added the 10g butt cap. Strung with Wilson Extreme Syn Gut at 58 lbs.

Comments: This racquet is a gem. After playing with it for 9 months I have yet to find something it cannot handle well. It is a great weapon from the baseline and is very stable at the net. Although it feels most at home on flat shots, it can easily produce good spin and it is most definitely a slice machine. Having switched from the Redondo Mid (undoubtedly the easiest racquet on the arm) and the Prince Diablo Mid + (a very solid racquet) I feel that the Platinum is where it all comes together. It even allows for better court penetration than any racquet I have used recently. Truly a gem!

Comments: Good solid racquet, felt good on flat shots, more forgiving on off-center shots because of bigger headsize, has good bite on backhand slices, can produce decent spin (had to put little more effort and this may be because of tighter string pattern) and effective on flat serves. Felt little heavier and even though it gave good control it somehow felt like a board on many shots.

Comments: After testing this racquet for about 3 weeks, I made the switch from a slightly lighter Head Youtek IG Speed. I tested the Red 99 last year and liked it about as well as the Head, but I'm a fan of the tighter 18x20 string pattern I love the mass and head light balance of this racquet, but more than anything- the smooth, solid feel is just addicting. Baseline shots are like carving through butter with this racquet, solid, smooth and powerful. Volleys are so solid- even with slightly off center contact and serves are much easier and more powerful. Just can't say enough about this racquet.

Comments: Play tested this racket for over 6 hours now and I'm coming from rackets of almost identical specs. Superb feel, comfort, and control especially at the net. Power is decent, service is deadly with pin-point accuracy. I prefer head light hefty rackets (9/10 pts. thereabouts) so I put on the 10g. butt cover from customizing kit to increase maneuverability and decrease swing weight. All told, I'm very pleased with this stick.

Comments: As others have said, this racquet is very solid. It truly is amazing at net. Its heft is not a problem, because it forces me to hit through my shots. My previous racquet was the Babolat Rafa, and it was so easy to get wristy. This one rewards me for good technique. Because of its plow-thru, well hit shots are deadly. I helped the power and spin a bit by using 18 gauge Black Code at 51 lbs. Very happy!

Comments: This has more controllable power than the X-99 Black. With the Black, the ball would fly on me sometimes, probably because of the more open mains (16 vs. 18). The Platinum allows me to take huge cuts at the ball without sending it long. Incredible topspin potential and excellent for generating penetrating slices. The plow through feels as good as the Wilson BLX 6.1 18x20, but with more comfort. The thin beam allows for awesome racquet head speed.

Comments: I am a 51 year old former collegiate player that hits with classic flat groundstrokes and plays an all court game. The Donnay Platinum 99 is a huge improvement over the first generation of Donnay X Dual Core Racquets. The Platinum 99 is much more solid than the Red or the Black especially on off center hits near the tip of the racket. Also, the Platinum 99 has more power than the earlier versions at lighter weights. This is a fantastic control racquet from the baseline (slice is amazing with this racquet), is solid and easy to maneuver at the net. Serving with the Platinum 99 takes some work. You will not get the easy power that comes from a wide body racquet. You can get power on the serve but you really must attack the ball. Overall, this is an excellent racquet for players that want more control and can generate their own power. Strongly recommend giving this one a try.

Comments: This is a very good racquet; serves are great, ground-strokes good, stability is amazing which translates to one of the best volley racquets I have ever used. Having said that, there are a few problems. Firstly, the balance should be more head light, I don't want to make the racquet heavier so I can't add the heavier butt-caps. The spin on this is not great; 18x20 string pattern feels like a board which for me translates to a dead feel. Don't get me wrong though this an excellent racquet. I would recommend this to a person who hits very flat and goes up top the net a lot. If you are an all courter who uses lots of spin or a pure baselined, especially one who uses spin, I would recommend the X-Dual Gold 99. This Platinum 99 is a great racquet; I just wished I chose the Gold 99 instead.
