Comments: This is an update to my earlier review in April. I still consider these balls to be excellent for the money for match play. The pressure noticeably decreases by the third set, but not any worse the the Penn and Wilson balls at the same price point. However, they won't be good for a second match so if durability is your thing, I recommend spending a little more and buying Pro Penn Marathon. Another thing I like about these balls are they are ready to go and I'm able to hit big shots in the first and second games. Other brands seem to have a longer break in. These, in my opinion, are the best value and a decent ball that suits a lot of playing styles.

Comments: At first, I found these tennis balls to be a little soft. I was a little skeptical, but after a few days of practice, they have a nice feel. Good all-around tennis ball. It seems like they need to be broken in slightly.

Comments: The Dunlop balls are great for teaching and last a good month before they start to lose pressure. For the price I found these to be exceptional balls, spending $90 a case is not an option when going through 20 cases a summer.

Comments: I found these balls to be fine at least for outdoor play in Southeast Michigan. Despite some negative reviews, I decided to try these since the price was right and there is free shipping. Three cans in versus three different opponents with varying styles and none of us have found anything wrong with these balls. They seemed to keep their pressure and didn't have any noticeable defects. My last opponent remarked that they don't feel as bouncy as standard Wilson or Penn balls, but it's not necessarily a drawback. If the rest of the case performs as the first three cans, I can certainly see myself being a repeat buyer.

Comments: Stiff, very little felt, fast. Gone in 45 minutes.

Comments: What happened Dunlop! Recent case of these seemed to have more cans open up on the flatter side. One new can I opened, went to bounce a ball to my wife, and it barely bounced at all. I just threw it out and tried another can, it was slightly better. Across more than two cases almost no issues, recent case seems of much lower quality overall, across almost all the cans. With the recent order being so bad I'm thinking of switching to either AO, US Open, or ProPenn to ensure a consistent product.

Comments: Love these balls for my academy! I disagree with the comments by Steve, Anderson, and Mark. These are not premium balls, they are extra duty, heavy, fast, and designed for advanced players 4.5 level or 8 or higher UTR, that pop two cans per match of one every 45 minutes. I use a new case each week for live ball play with the top juniors in my academy. After that they are transitioned to machine balls and last three to four months, good value. I typically have 1,500 balls for the intermediate junior players to practice with the machines because they need reps and these balls are consistent plus cost effective. After three to four months they are transitioned to beginner serving balls with the same intention, reps. Regular Duty balls lose 30% more speed after the bounce that Extra Duty balls. Comparing these to a premium, more expensive balls like Wilson US Open Extra Duty isn't fair because these cost 30% less. The key to making your balls last is store them in air tight and locking bins. I recommend rubbermaid containers because they won't crack, last forever, and really keep the humidity out, which zaps any ball. Storing balls in a hopper isn't ideal even in climate controlled areas. For my use they are far better than Penn Championship Extra Duty balls. I am a former ATP World Ranked player with 34 years experience playing and coaching world class juniors and pros.

Comments: Have been using these off and on and I find them to be great balls. Much more reliable and longer lasting than Penn Championships. In the two or so cases I've ordered I can only remember one can that felt heavy when new but I think would lighten up with some hitting. Overall I find these to be a higher quality and value than Penn Championship balls and would order them again. Just for comparison my favorite tennis balls are ProPenn, Dunlop AO, and US Open. In the current pandemic era of tennis, where balls are not used as much, these are a great price point that I feel less guilty using a few times and recycling.

Comments: I wanted to to try a new case of tennis balls for teaching high level junior other than Wilson US Open XD tennis balls. Seeing the reviews and the lower price point of these, I bought four cases. The first two lessons I had were fine, although they were a bit soft. However, after those first two lessons these balls were just absolutely dead. Like green dot tennis balls kind of dead. I was so disappointed in these that I sent the remaining three tennis ball cases back to TW. I could not use these for my lessons, it would be unprofessional. I am going back to Wilson US Open XD tennis balls. These are okay if you are playing a match, but do not use these for teaching competitive players in my opinion.

Comments: These balls are way too hard and fast. They feel cheap and are not arm-friendly.
From: DK, 7/22/20

Comments: We bought six cases for our high school team this spring. Quite possibly the worst premium ball I have ever played. The felt on these balls is thin and mats down immediately, and as such they are noticeably smaller than other balls. There is virtually nothing for your strings to grab onto to generate any spin and they tend to fly. The bounce right out of the can is comfortable, but they feel soft and almost flat way sooner than other balls.

Comments: These come in 3rd compared to Penn and Wilson Championship balls in my opinion.
From: Brad, 11/1/19

Comments: Bought these as an alternate to the expensive US Open Wilson's or ProPenn's, and disappointed. They hold pressure longer, but the felt and carcass is thin right out of the can. One set, and these are as thin as a one month old practice ball. They seem smaller in diameter than the better balls, less felt, and much harder to hit. You won't get much bite on these with less felt, and you'll feel the hardness through your arm and joints every time you hit one. I have half a case left, and they'll be used for practice or warm-up only. You get what you pay for. I'll buy ProPenn or US Open Wilsons from now on.
From: Anderson, 9/30/19

Comments: Very nice ball, consistent bounce and so far seem to be holding up well. I like these better than the ProPenn balls and Wilson US Open balls.
From: Kyle, 7/25/19

Comments: For basically $2.50 a can, these are really good tennis balls. I've logged a few games with two cans already and they are holding out quite well.
