This is a revolutionary year for HEAD Racquetball in both looks and technology.

These racquets will play less stiff than the AMP racquets and more stiff than the Extreme. At 165 grams unstrung the Problem Child is a very powerful racquet ideal for the power player or intermediate level player.

Comments: I demo'd this racquet along with Head Ares, Scorpion, and Great White. For reference...I'm 5'10", 190lbs, 48yrs young, and in excellent overall shape. I've been playing racquetball regularly for approx. 3yrs now. Most would consider me a very good B player at this point.  I choose to demo the Problem Child after warming up with a friends (also a very good B player). He loves his Problem Child and has had it be faithful without breakage for @3yrs and going. Warming up with a racquet is one thing, playing in a competitive game is another. And after playing games with this racquet I can confirm for myself the following. Pros: It's a very comfortable swinging racquet with very good maneuverability. Superb control! Above average power, but nothing like the Scorpion I demo'd. But if you can swing hard the power is more than enough. I also really think it's a great looking racquet in person.  Cons: As I found with my friends Problem Child, this demo also has on certain hits a "hollow" feeling vibration. The shot still makes it as intended but it just feels strange and took my mind of the next situation briefly as my brain was going "?" It's a small issue really but it's there. I'd imagine it can be dampened and made a non-issue I suppose. Other than that the ONLY other negatives I can give it is I wish it was ever so slightly more maneuverable and wish it had more authoritative power on tap without having to swing as hard to gain it.  Bottom line: My second favorite of the four demos (Look for reviews of the others to see my winner and loser). The Problem Child was a real strong contender but a contender nonetheless for me. Having said that, it's definitely a racquet I could live with and play strongly with. Highly recommended for the control game type player. Thanks and hope this was a useful review.

Comments: I love this racquet. It's light, fast and powerful. Sweet spot does feel a bit small, but off-center hits for me result in looping shots that usually drop on walls just perfect. I know it's a miss hit, but my opponent doesn't. My favorite is getting the racquet under those hard to get to back corner shots, just when my opponent gives up I drive a low fast one to the front wall. The only thing I wasn't fond of was the grip. Sadly I cracked my first one, or it cracked. I don't believe I did anything to crack the racquet, as I'm cautious around walls. Head graciously honored the warranty and replaced the racquet free of charge. Just increased my faith in head products.

Comments: I just received this racquet yesterday and played with it for a couple of games.  My previous racquet, a Ektelon O3 Red, after two years of use finally cracked. After hitting with my roommates Extreme 180 I decided I would give Head a go.  I love this racquet because of the power but my accuracy has taken a hit because I'm still adjusting to the head heaviness of the racquet versus the balanced O3 Red. I imagine my play will improve with time as I grow accustomed to this racquet.

Comments: I went from E-Force Super-DC 30 (after the frame cracked from years of hard use), which I was very happy with to the Head Problem Child.  I could not find a current E-Force demo that I liked so I switched to HEAD.  I am very happy with the Problem Child.  In play it feels the same as my old Super-DC 30.  Although 5 grams lighter at 165, it plays the same because the weighting is a bit more toward the head.  At first I felt no difference.  After some time though, I think the control is a bit better with the HEAD racquet.  Power feels similar to old E-Force.  I hit very hard and my only complaint is that I've gone through the factory strings and two sets of 16 gauge gamma strings in two months.  Hope this is not a trend...

Comments: HEAD never ceases to impress me.  I own the EXTREME 170 and absolutely love it.  This racket, though, is even better.  The lighter weight makes backhands more fluid and the pop is unbelievable.  Power, control, and placement consistency are tremendously improved with this racket. I bought it...and I will buy another! Anyone who says the all the new racket technology is marketing hype just got proved wrong.  I can't wait to demo the new DECK series rackets!

Comments:  I used to play NOTHING but the E-Force Bedlam and/or Stun series for several years.  I enjoyed the power, and although the control with them seemed OK, it was nothing to write home about. I just knew that my previous Ektelon Racquets were killing my elbow and the switch to E-Force had stopped my elbow pain, several years ago. I currently have one Bedlam Launch Pad 170g (primary), and two Bedlam Stun 170g's (backups).  If memory serves me correctly, they were bought in about 2006.  So, needless to say, it is "time" for some new sticks, as my current arsenal has led a good life. After a VERY bad experience with the HEAD Intelligence 165g a few years ago (power/control/string life issues), I was hesitant to try another HEAD racquet, and I had every intention of staying with E-Force. However, three main issues made me re-consider: 1.  The dwindling numbers of people playing E-Force here locally, as they have been upgrading from one E-Force racquet to other racquet brands, rather than upgrading from one E-Force racquet to another E-Force racquet. 2.  My racquet shop where I get my racquets re-strung is not willing to carry E-Force products due to reported Customer Service issues. 3. A friend who has been raving about his recent switch to HEAD equipment after many years as an "Ektelon only" man. So, I decided to give it a go, and... The Problem Child has made me a converted man. The phenomenal combination of power AND control was STUNNING, to me!  (Please pardon the pun.) Placement was almost effortless for me, and the power was at least equivalent, if not better than my current sticks.  It was fairly soft but still very firm on impact, and quite comfortable. I was scoring points today on shots with the Problem Child that would have never made it off the face of one of the current racquets I have been using! I will be looking to completely switch over from E-Force to Head over the next couple of weeks as I get the funds together to buy a couple of racquets, a bag, gloves and the accessories! HEAD has won me over with this one!  I am VERY impressed!

Comments: I used to play with an E-Force Command Powerflex 160 but when I switched to the problem child after a break in my Eforce I noticed similar power levels with huge increases in control and better power/control for off center shots. Its great in the front of the court, quick and light. Great Racquet, I've played with the extremes 170 and this is very similar just a small step up.

Comments: First off, I must say that I favor Head over any other racquet because of the great feel. I'm 51 years of age and although I have good power, my game is really a finesse one. I regularly beat guys half my age because I can control every shot and have a wide range of them. Each season, I try all the new gear to see if any of them have control but maybe some added power. Well, after being VERY disappointed with Head over the last 3-4 years, this racquet is that perfect mix. No where near the power of the latest E-Force or Ektelon's but it has the right mix of head heaviness that I like but an additional 15-20% more power. You might laugh, but I still play the old Head Megablast 175. This is the first racquet in a while that has the same balance and firm feel. Must be used with a dampener, it's really a quiet axe in your hand. Not super fast, and a smallish sweet spot but elegant in its mix of power and control. I win a lot of points because I can hit a small spot on lobs and serves. This baby does that so well. Where the added benefit was for me was that at 38 FT, drives shots were so effortless. Perfect weight at 165 for me (I liked the Meanstreak but the added 10 grams made it feel a bit sluggish on half volleys). Anyway, the poor guys at the gym are ticked cause they all noticed it last week. This racquet will no doubt secure my #1 rating for a bit. Thanks, RW.

Comments: This is a great racquet. It feels much better than the Amp 175, easier to swing, and more forgiving on off-center shots. You can get plenty of power from the low weight and head heavy balance. I really don't have anything negative to say about this one.

Comments: I have used the Liquidmetal 170 and Extreme 170 for 18 month and never had a problem. I bought back in June the Problem Child 165 and in less than 30 days, trying to get a ball from the wall the racquet cracked. I got a replacement in 30 days approx. Now I used my new racquet for about a month and cracked again. I hope this is covered by the warranty too. I would not buy this racquet again since it breaks easily.

Comments: Had a chance to be one of the first to demo this racquet and I love it. I have been playing with the Extreme 170 for more than 2 years now and it is a great racquet. The Amp, just did not "do it for me". The Problem child is a step up or an improvement over the Extreme. It plays strong even when hitting off center. Great POP and swiftness. This is a true winner. My son loves this racquet and will be using it at Jr. Nationals.

Comments: I have had the chance to hit with this stick since the demos were out last summer, and now I can finally comment on its spectacular amazingness. Stiffer than the Extreme, not as stiff as AMP, lighter weight, higher in power, everything that needed to be altered from previous models was addressed, and they truly have an amazing racquet this season, GET ONE.
