What players say

Coverage of this exact 300g Ki 15 is thin, limited to owner reviews on Tennis Warehouse's US and Europe sites rather than major press or video playtests, but the owners who've strung it up are enthusiastic. They describe easy, ample power, a big forgiving sweet spot, and genuine arm-friendly comfort, with the main gripe being that power can be almost too easy to access without a control-oriented string or added weight.

Best for

  • Players wanting easy power with arm-friendly comfort
  • Doubles or serve-and-volley players wanting stable volleys and a potent serve
  • Players managing tennis elbow or arm sensitivity
  • Players open to adding weight or a control string to tame the power

Pros

  • Easy, ample power out of the stock frame, especially noted on serves
  • Genuinely comfortable and arm-friendly; praised specifically by a player managing arm pain
  • Big, forgiving sweet spot with a crisp feel at contact
  • Good shot versatility, with owners calling it strong for topspin serves, slice, and drop shots
  • Crisp, confidence-inspiring volleys

Cons

  • Power can be almost too easy to access, making it harder to keep shots in the court for at least one owner
  • Some owners paired it with a control-oriented string (e.g. a multifilament) to rein in the pop
  • Extended 27.5" length takes adjustment time for players used to standard length
  • Owners comparing it to other brands added lead tape to match familiar specs, suggesting stock swingweight/balance feels unfamiliar out of the wrapper
  • Very little independent or video coverage of this exact 300g version exists outside of retailer owner reviews

Voices

The power is so easily achieved, volleys are crisp and really puts a lot of pop on the serve.

This racquet is very powerful and very comfortable and arm friendly, you just need to put a string on it like Technifibre 17 bi phase to control the power.

— Hamid, TW customer review (FL), Web

Great for topspin serves, slice shots and drop shots.

— Selles Morris, TW customer review (FL), Web

Wow! I added lead tape to get it a little heavier to match specs to my Babolats and this is a dream!!
