Comments: Well first off, I loved this racquet for the 9 months I had it until it cracked and shattered on a flat serve I did at State Championships. But besides that, I loved it. Thought it was a little light so I added lead tape to 3 and 9 o'clock and the handle. I had RPM Blast 17 in it at 56 pounds, felt great and I could use a lot of spin and power. My forehand is what got me to state and this is the racquet that did it for me. Thank you Wilson.

Comments: Absolutely love this racquet. Wilson's 'Four' series racquets would be my racquets of choice, but unfortunately, the Tempest Four BLX destroyed their heritage, and a K-factor would be a bit of an anachronism in advanced-level tournaments. This is a wonderful racquet for all levels; one of very few that a player can use as a beginner and use it all the way almost to the tour without switching. For advanced players, I would strongly recommend trying this stick at high tension with some nice, stiff kevlar or poly. I would generally write a brief review of a racquet I've tried, but for this, there's really no point. It's the best on all fronts: Serves, volleys, tweeners, you name it, this racquet delivers it with pace, spin, and precision. Simply phenomenal. I sincerely hope that Wilson releases a Tempest Four BLX 105. All in all, this is a great racquet (although it's outdated, it'll be worth the demo). Leave it to Golovin to find such a superb racquet as this, and I wish her a speedy and painless recovery.

Comments: It's the best racket I've ever had! I'm very pleased about this stick. It's very light and maneuverable and it also has a lot of [k]ontrol. All the serves are very accurate and powerful. I really recommends this stick to anyone who wants a good racket and a game full of [k]ontrol.

Comments: Very good racquet, particularly when demonstrated by Tatiana Golovin. It allows her to have an all court game while also having a huge serve and forehand. She can apply topspin very well when needed and uses this racquet to her full advantage. A+

Comments: Groundstrokes are amazing with this racket. I am able to produce a lot of power and spin without having to use much effort and without losing any control. This racket has tremendous touch and feel; you can produce excellent slice with this and the ball really knifes across the court. Volleys are effortless and smashes are super! Serving is very good and easy to find pace, and I am able to produce a lot of topspin. I was using the Wilson nCode n4 OS before trying this, and I found the k four much much better on volleys and slice, and over all, better. I would recommend this to anyone looking to improve their game, and to any strong baseline and forecourt players. 10 out of 10!

Comments: Very light racquet. I was surprised that I can get more power out of it than I thought I would. My slice serves were in accurate, backhand was a little off but over all this racquet is great.

Comments: I demoed this racquet today and I absolutely loved the feel of the racquet. Racquet seemed to have great forgiveness and gave great spin and slice on the ball, however, seems to lack power. My serves are usually flat and hard and with this racquet I was very accurate but there was not a lot of pace on the ball. I also have a very full swing and I seemed to hit the ball out a lot when I really hammered the ball. I would love to purchase this racquet but I am going to try the KZen and a few others to make sure I am finding the best racquet for my game. If this racquet had more depth and pace on the ball, I would be sold!!

Comments: Awesome racquet. It is great on groundstrokes, especially the backhand, and is wicked on volleys. I am loving the control. I love the weight as well. I recommend this stick greatly - it's just oozes class.

Comments:I find this racquet a little more stable, more stable than the ozone seven since this racquet has so much more maneuverability. I liked the [k]ontrol a whole lot on groundstrokes. Serves were like Tatiana Golovin's herself. My backhand two handed and one were both kind of hateful though. Net play was coolio like polio. Anyway, worth the buy.

Comments: I love this racket! It has good control yet it doesn't sacrifice that much power. What I love is that when volleying, it's so forgiving. I love it.

Comments: A great stick. It enables me to take a big swing and never hit long; backhand took a couple of days to break in, but my serve has never been this sharp or accurate.

Comments: Stable frame, just heavy enough to handle pace. Take note of the stiffness, has a higher rating than many other sticks. I'm a 27 yr old who got tennis elbow right after purchasing this. Could be coincidence. Serves Great, thought it would generate more power for me, more like a players stick.

Comments: This racquet has great balance and feel. I also liked the Zen Tour but found that I had more pop on my serves and volleys with the KFour. I am coming off the Wilson Hyper Hammer 4.3 and have tried several other racquets, none gave me the feel I needed. This is a great stick
