Prince Hydrogen 300 Racquet Review
Looking to make a statement on the tennis court, Prince teamed up with Italian apparel brand Hydrogen to create some fashion-forward cosmetics for its racquets. For this review, the TW playtest team tested the Prince Hydrogen 300 in not just one, but two cosmetics: Random and Spark. Although they look different to the eye, the specs and technologies are the same for both. It didn't take long for our playtesters to find their groove with the Hydrogen 300. The racquet features classic tweener specs, including a 100-square-inch head size, 11.2-ounce strung weight and a 320ish swingweight. Right off the bat, the testers found the racquet easy to use and swing. Additionally, there was plenty of access to power and spin on every shot. As the month-long playtest wrapped up, a couple of testers noted the need for a little more control and some instability when stretching to reach a ball. Overall, though, the Prince Hydrogen 300 is a user-friendly racquet for a wide range of players with some of the most fun cosmetics on the market.

Groundstrokes: 8.1
The Prince Hydrogen 300 offered an easy transition for our playtest team starting with groundstrokes. Brittany has a long history with Prince racquets, dating back to when she first started playing tennis at 5 years old. She said, "When looking at the two different cosmetics of the Hydrogen 300 and holding them in my hands, my first thought was that these are really fun and unique. They are definitely cosmetics I haven't seen on a racquet before! Also, looking at the specs, I was happy to see they were right in my wheelhouse. This made the initial adjustment during the playtest extremely easy. From the baseline, I found easy power and great spin potential on my groundstrokes. One thing that I appreciated was that my groundstrokes were landing nice and deep in the court thanks to a higher trajectory off the stringbed. There was a little too much power at times, and I found my groundstrokes sailing well past the baseline. I then utilized the spin I received from this racquet to help get my groundstrokes to dip in front of the baseline."
"I found I could be really effective from the baseline with the prince Hydrogen 300 and keep my opponents pushed back."
"Both the Random and Spark racquets have eye-catching, surprising cosmetics," added Tiffani. "Once I got on the court, I wasn't too surprised by how the racquets played. Rallying from the baseline came pretty easily, and I could generate good depth and pace from easy swings. I did struggle a bit once I started to play points, though. Because I tend to have more of a grinder mindset and hit a relatively flat ball, I found myself missing long before I could really get my opponent out of position. I needed to change up my game style a bit to try to end points sooner. I ended up really liking this racquet when I was transitioning to net. I could whip up spin and either hit an outright winner or put my opponent in a tough enough spot to get me an easier ball to put away at net."
Zsofi is a big fan of the Hydrogen brand in general, and she was more than a little intrigued when she first saw this racquet. She said, "Because of the unique design, I thought this was a very cool setup for a racquet. Like the others mentioned, the Hydrogen 300 features very user-friendly specs, and it is easy to adjust to. I found easy power from the baseline, and I was able to get my shots deep in the court without much effort. The launch angle is pretty high, so that is something I had to dial in a bit to avoid overhitting. I also had to be especially mindful of this launch angle on slices to make sure they stayed nice and low, so it did take a bit of time for me to make the adjustment. Thanks to the open string pattern, spin was really easy to generate, so if you are a player who prefers a racquet that can add that extra pop to your shots, this frame is a good option for you."

Howard felt right at home at the baseline with this racquet in his hands. He said, "I enjoyed hitting groundstrokes with the Prince Hydrogen 300 racquet in the Spark cosmetics. This was the type of racquet that I was able to jump in and hit with little to no adjustment. The racquet did lean more toward power than control, but it still had enough accuracy that I felt confident laying into the ball without worrying that it would land out. The Hydrogen 300 held up well when exchanging power shots with an opponent, and I had little to no issue with stability. This frame was a great plug-and-play for my current game style."
Volleys: 8
When it came to volleys, the Prince Hydrogen 300 featured a large sweetspot and plenty of put-away power. Howard found success ending points up at net. He described, "Volleying with the Prince Hydrogen 300 was enjoyable. Punch volleys came off the racquet with a good amount of pace and power. Even when I would mis-hit my volleys, I would still get a decent ball back, making this racquet forgiving on off-center shots. Maneuverability at the net was not an issue, and I felt confident getting the racquet into position when opponents would hit a drive toward me. Overall, it's a solid option for doubles and singles play at net."
The Hydrogen 300 immediately clicked for Zsofi at the net. She said, "Because of the big sweetspot, volleys felt easy and comfortable, and I found easy depth for my shots."

This racquet offered a forgiving response for Tiffani. She said, "Although I experienced a little instability at net, I was overall very happy with how I could volley with the Hydrogen 300. The racquet has a big sweetspot, and I could get it into position easily. It perform well when I was punching my volleys deep into the court."
On the other hand, Brittany didn't fully gel with the feel that the Hydrogen 300 offers. She explained, "When I approached the net, the feel of the Prince Hydrogen 300 caught my attention. After a couple of warm-up volleys, I noticed the feel was slightly different than what I expect from a Prince racquet. I found the Hydrogen 300 less dampened than what I am used to, especially from Prince. This translated to more feedback and a better understanding of where the ball was landing on the stringbed. On the other hand, it wasn't as comfortable, especially if I hit off center. For the most part, I kept it simple and punched my volleys back deep to end points.”
Serves: 8.2
Our team found that the Prince Hydrogen 300 provided easy power and spin on both first and second serves. Zsofi's highest scoring stroke was the serve. She said, "I thought the Hydrogen 300 really excelled at serves. I was able to get nice net clearance and easy power on my serves, so I felt very confident when I was hitting them.”
Howard continued to sing the praises of the Prince Hydrogen 300. He said, "As with everything, serving was a delight with the Prince Hydrogen Spark. It has enough mass to hit a strong flat serve and enough maneuverability to cut into the ball for a good kick serve. This racquet felt automatic when I had to hit a second serve; I had very few double faults."

"On serves, I liked that I had no issues maneuvering this racquet," added Brittany. "I was able to get it up and over my head with ease and could generate a good amount of racquet head speed. I was also able to maintain the racquet head speed over the course of a match or practice session without any arm fatigue. There wasn't anything special that stood out, but I was able to do everything I needed. I could hit a flat first serve or come around the ball for a slice or kick serve. Like groundstrokes, my serves were landing deep in the service box."
After a small adjustment period, Tiffani was able to dial in her serves. She said, "There's easy net clearance on serve, and it took me a few practice serves to find my depth. I was missing long, and I discovered that I could carve around the ball pretty well to get some nice spin on my serves. My favorite serve was slice out wide on the deuce side."
Returns: 8
There were some mixed responses from our playtesters when it came to returning serves with the Prince Hydrogen 300. For the most part, Tiffani felt like she could hit some good returns with this racquet. She said, "I like to think of the court as two halves and just pick one side and go for it. I appreciated how this racquet came around quickly and I found it easy to hit with depth. I did have some issues with stability when facing heavier serves.”

Like with most racquets, Brittany preferred returning with the Prince Hydrogen 300 over serving. She explained, "I thought this racquet did everything I needed it to do. I was able to get it around my body, step in, and take a good cut on my return. I made sure to add a little more topspin to keep from overhitting. I also noticed the feel here (similar to volleys) when I didn't hit my returns exactly in the sweetspot. I ended up making a small adjustment to my string setup to fix this. While I typically use a full bed of polyester strings, I changed to a multi/poly hybrid halfway through the playtest, and this helped enhance the feel and make the racquet a little more comfortable overall.”
For the most part, Howard enjoyed returning serves with the Prince Hydrogen 300. He said, "Everything on returns of serve was great except when I was reaching for a return. When I was stretched out wide, the racquet did feel a bit unstable. I would get the ball back into play, but it was a poor ball that my opponents could capitalize on. However, I was able to be the aggressive player on about 90 percent of returns due to the easy power level the racquet provides, which helped me take control of a point early."
"Since the Hydrogen 300 is generally very easy to play with, returns were comfortable, and I was able to get easy depth. "
By aiming a little on the conservative side, Zsofi was able to start the point off offensively on the return. She said, "I chose to hit some safer targets with my shots, mainly because of the higher launch angle."
