E-Force Invasion X 160 Racquet
+ Demo Racquet

Invade your opponent's game with the E-Force Invasion X 160!  E-Force has improved on their previous line by re-engineering their Power Boosters to improve dampening which, when paired with the Quadraform head shape, gives you explosive power from the stringed and more comfort on off-center shots.  Of course, E-Force has kept their other patented technologies in the frame to ensure that they're putting out one of the hardest hitting frames on the market.  Once you get this frame in your hand, you'll know the meaning of power and send your opponents into retreat.

Comments: First, I have to say I like playing with the racquet. It has a lot of power and good control. The downside is I have broken two grommets on two frames. The first one broke after one week and the second one broke after 4 months. Both broke in one string hole. I didn't notice the first one right away and the string started cutting into the frame. Fortunately, the seller just gave me a new frame. The new frame had the same problem today, but, luckily, I caught it early and will just have the grommet replaced. I can't really say what caused them to break. I don't have a lot of experience with other racquets or previous E-Force racquets. Anyway, if you buy this frame, hopefully, you won't have a similar problem.

Comments: Great Racquet.  The grommet broke, however, after couple games.  The string followed during the next game.  Sent it back.  RbW put a new string with which I have been playing for over a month (3 times per week), now.  The grommet has failed again, but the string somehow holds on.  Will see how long?

Comments: Received the invasion 160 on Friday and broke the frame on Saturday. Didn't hit walls or floor. I really like the power of the racket but there appears to be an issue with the frame

Comments:  I had the same experience with a new invasion 160. It broke in my hand just hitting forehands while warming up.

Comments: I was loving my new Invasion X, only 3 weeks playing with it and when I was warming up just hitting forehands, the frame broke !!! Another guy in the same gym experienced exactly the same thing, brand new, and his racquet just broke when hitting the ball. Please beware of this apparent factory defect.

Comments: Hardest hitting stick ever. Feels great, balanced a little head light from last year.  Another fine creation from the folks at E-Force

Comments: I just tried the E-Force Invasion X 160 and it does have lots of power and control in the Quadraform frame, it's stable enough; hope the frame doesn't break as easy as the regular Invasions.

Comments: For a 160g frame this is the heaviest racquet on the market at 205g strung...ouch.
