Comments:I tried it tonight and I have to say I was playing some of the best tennis I've ever played with it. To me, this racquet has the right balance, headsize and weight that it helps me get the extra power and maneuverability that I was looking for. The string pattern also helps me get that extra spin that I was looking for. Unfortunately, I think my serve loses a bit of weight behind it due to its light weight. My touch volley also wasn't working, but maybe I just need to get used to it being slightly head-heavy. These are minor downsides that I have no problem having compared to the gains.

Comments: The racquet is very light at 9.6 oz. It's frame is weak but it can play excellent. This is my second time playing with the racquet that I received the other day and I love it. The K Factors' made by Wilson are very outstanding and I would recommended this racquet to any skilled player that has played for three years at least. Anyways I've been playing for only two, but my coach has told me that I play very good with it and that it is an outstanding racquet. I play with a 3/8 grip and it is awesome with Wilson Tacky Overgrips on it as well. Give the racquet a chance and try it out, you will like it!

Comments: Great racquet. I actually was able to win few tournaments with this stick. I used to have Pure Drive GT Plus and this Kfactor can't compare with it...... AMAZING! Tennis warehouse also delivered this racquet fast, and it was perfect to go! Thanks, TW!

Comments: I bought this racquet because I wanted a light frame that was slightly oversized for a good price. I must say this racquet is great so far! First off, the cosmetics on this racquet look wonderful. The paint job is great. (It doesn't help your game, but it's a plus.) With the larger sweet spot I felt that I could hit a ball off center and it would still find its way in the court. The larger head made my first serve more consistent and powerful with a lot less effort. I was rallying around with one of the local tennis teaching pros in my area and I was able to stay in longer rallies with the guy. Every time I would hit an out ball it was always because I wasn't in position or I was being straight up lazy, nothing to do with the racquet. The racquet is also very spin friendly. My topspin is a big weapon of mine and the oversize head really helps when you hit up on the ball. The power is also great with this stick, and it doesn't take much effort to obtain it. The only down side is the control. I think next time I get my racquet strung I'll have to have some higher tension because the oversize head doesn't allow for much control. I think after a month of hitting it, I'll find my range with it. Great racquet!

Comments: It is a pretty good racquet overall. It is very light and good for controlled shots and it has decent power. My shoulder and elbow problems were gone after first use. Overall, good racquet for a great price.

Comments: I've had this racquet for over a year now and although I originally loved it, I now have second thoughts. I've recently demoed a couple racquets and I can tell the difference immediately. I am much less erratic, and have more control that with the K Fierce. I think it's great for someone in a transition between recreational and competitive, but there are definitely better racquets out there.

Comments: I have had this racquet for 2 weeks. I found it to be very light and comfortable racquet. For it's price it's an excellent value and very nice, light and response racquet. I would recommend it with any hesitation.

Comments: This is a really good racket! The main reason I wanted to buy this racket is because of the low flex rating. I am very happy with how "soft" the racket feels. So, if this is something that is important to you, this racket is one you should try. This is also one of the easiest rackets that I have ever played with. I almost don't have to worry about watching the ball as much as I do with other rackets. The racket is very forgiving overall. I like this racket a lot because I can be really late and still catch up to hit the ball on time. I also like that the racket has a lot of power; which means I can focus on hitting with spin, or just let the racket do the "work" of hitting the ball. I found the racket to be really easy to swing quickly and generate head speed. This is my first extra length racket and I did not find the extra .25 inches to be a problem to deal with.
Finally, I like the fact that when I take this racket to the courts people think that I am a beginner... and then I strike! Vamos!!!

Comments: Just hit with this racquet for the first time, and I was NOT disappointed. I worried this frame might be a little too powerful for me, but it was just right. Great depth and power from the baseline, as well as a surprising amount of control. I was picking my spots pretty easily, and I found this racquet to be especially useful when really driving through the ball. But also supplies an ample amount of topspin too when needed. All in all a great racquet for the price!

Comments: Good power!! Excellent price! I bought this racquet for my friends that are just starting to get into tennis. This racquet has a large sweet spot, and a great feel. Overall, great deal!

Comments: This is a good, lightweight racket. If you are looking for power and control, I think this is a good choice and the price is just right. Because it is light wt I am able to generate a lot of racket head speed. It is a good all court racket for a senior player because that extra power will help you make that transition game easier. I used to play with a Wilson hammer 6.0 and I prefer this racket now because it is a little head light, so it is better for someone with a complete swing. Overall, I am quite happy with this racket.

Comments:This is a pretty good racquet, although I have trouble getting as much control as I would like. It has a very large sweat spot and is a very maneuverable frame, however this is my first full sized racquet so I do not have a lot of comparison.
