I am officially blown away by Vivo 1.28. One of the best if not the best shaped string i ve ever tested. I didn’t like sync, zero and neither the hybrid between them. Vivo on the other hand is sth else:

-The best crisp sensation you ll ever experience in the market. It takes crispness to another level. From the first hit, feel was so addictive as so the way ball sits, slides and releases.
-Unlike those super SnapBack-y torolines and zero, Vivo is closer to legacy poly strings. You usually know the outcome and what to expect….. no many unexpected ball takeoffs. I only need more time to connect better with the defensive slice.
-The way it bytes/couples and carries the ball gives such a satisfying sensation that translates in added confidence to go for it.
-amazing accuracy on flat serves.
-launch angle in ground strokes not extreme
-power potential very balanced between what you put in and the amount of help you get from the string. I would label this string sth tiny bit higher than control strings.
-it doesn’t have the slippery or the artificial sensation of zero neither the stickiness of sync. I would say that it plays more like a sharper and more powerful sync or a softer pure rush.
-the great thing of Vivo is that it has the zero movement and great SnapBack of those next gen strings without messing with your swing style….. it’s very predictable and forgiving in that area.

I ordered a bundle of 5 last month when Vivo first came out and I think it's been their best string yet. A really nice feel to the ball. I like firmer strings and this one lands right in the sweet spot because it isn't too lively and you can feel how well the ball pockets. Tension maintenance is also very good, I'd say on par with Zero.

These keychains are so unique and I love the initiative behind them. I never knew you could recycle tennis strings in so many different ways and these keychains add such a nice touch to my tennis bag. Honestly 10/10!!

I've always played with stencils on my racket because it adds that extra look to it. Stencils are always made out of plastic but I was surprised to see this one was made out of paper. It's quite thick, so it doesn't bend, and has a nice premium feel to it. Also it doesn't get ruined with wet ink, so really well done!

I am a tennis string fanatic and playtest pretty much everything out there . Vivo surprised me, it's a very high level poly competing with my favorite string Solinco Confidential. Good feeling on the ball and even getting slightly more spin. For me this is a solid performance string and going to use it in my USTA league this summer. I am a 4.5 player and very happy with it.

I’ve been using Vivo for a few weeks now, and it’s been great! The tension maintenance is excellent, and it offers a great balance of power and control. I noticed improved spin and better feel on groundstrokes versus Solinco confidential. It string holds up well even after several sessions. Highly recommend it for players looking for reliable performance.

I have never played with hybrids before and was very sceptic on the real advantages. However, after trying zero on the mains and sync I found that the stress on my arm has significantly reduced, specially over long matches.

Im old school pro and use sync with gut. It is great. Superb control and feel. Tension stays constant and doesn’t cut into gut
Using sync for my whole team!

I've been using Lux ALU for years in a gut hybrid set up. the ALU goes dead in about 3-5 hours of play.

When I learned about Sync I though, eh -- another new kid on the block that promises a lot but how can it possibly compete with what many consider the best poly on the planet for decades now?

Well, I'm here to tell you that in my experience Sync is simply a better string. I have used it against ALU in a full bed and in a hybrid: and Sync has superb touch, pocketing, and feel; indeed, in my opinion it is better than ALU in in this alone.

But it gets better. Sync also seems to grab the ball and impart more spin when intended than ALU. It just does, and I suspect it has something to do with (in addition to the main factor, technique of course) the slickness of the string and the snap-back that enables. See here https://twu.tennis-warehouse.com/learning_center/stringmovementPart2.php: "The end result is that string movement and snap-back very strongly correlate with more spin."

For these reasons alone I prefer Sync. That slickness also means that it is very gentle on the gut strings.

But Sync also lasts much longer. The qualities it has last FAR MORE than 3-5 hours; I currently have more than twice those hours in my current racquets, and no sign of the dreaded ALU deadness whatsoever.

Thank you so much Restring for making such a phenomenal string!

Zero has been my go-to string for the past year almost. I used to go through through strings quite quickly, coming from hyper-g and rpm blast. Zero has been lasting me much longer and I've even switched to 17g to get extra feel. Highly recommend this string!

I bought Sync at the start of the summer for my USTA season. I was playing with ALU Power but the tension dropped after 2-3 hours of play, a friend recommended me Sync and have not looked back since. Really happy with the performance, feels great and I break the string before I begin to feel the tension drop.

I used to be an ALU Power fan but the tension dropped too quickly, with Sync the feeling is just as good and I can get 10 hours of play versus just 5 with ALU. Really happy to have this as my set up with my V-Core!

This is the third time I've purchased the Custom Box and I really like how I can mix and match Sync and Zero. I thought I would like Sync in the mains and Zero in the crosses but it's the other way around! The thinnest gauge of each feels the best. This is my set up for the fall season

I have tried just about everything under the sun, and man the tension maintenance, durability, and the damn SNAPBACK is insane. This string feels brand new after a week of hitting about 1-2 hrs a day. I have used it as mains in a 16 / 21 vcore, which played alright, however I would prefer it in crosses because the kirshbaum pro line I had in crosses notched too quickly. BUT, I then strung a full bed of zero at 54 lbs in a vcore pro 97 16/19, and my god it is the greatest string ive ever used. Specifically in regards to the tension , durability, and snapback.

Never have I seen a string so immune to notching. I am going to love to try sync as a cross with gama ocho tnt in mains for my father who needs an arm friendly setup, but hopefully can good spin out of the snapback from restring. My next test will be to put zero (and then sync) in crosses and hyper g in mains. Only becasue I like the higher launch angle of square shaped mains. Restring, maybe you wanna make a square shape string at some point?

Anyway you guys have here a game changing product imo. And my only regret is I got the 7 pack and not 7 reels!

Loved the attention to detail and quality.
Keeps its contents cool for hours.
