Triniti balls

Excellent. They stay firm with good bounce for long time - I lose them before they lose it! I have seen it said they are too firm initially but I don’t think that’s a serious problem and it is much better not to have to faff around with depressurizing balls. Great value.

Great quality tennis balls. They have a good feel and bounce. I play indoors and these are quite long lasting with no sign of wear after several weeks. P

These are good, they are *almost* impossible to distinguish from regular balls, but they last way longer (6-10h for a tube vs 2-3h for other brands), making them more economical as well as more sustainable. I will never buy any other balls than these from now on

These work well in winter when the temperature means other balls don't bounce as much and these bounce like a standard tennis ball does in warmer temperatures. However, in the summer these bounce all over the place. They do last longer than standard tennis balls and will last me a couple of months in the winter. I'm a mid standard club player.

Can’t recommend enough!The massive advantage of this compared to other standard pressurised balls I’ve noticed is that they don’t lose pressure staying idle and so are perfect for someone who wouldn’t use them very frequently (I play a couple times a month) but still wants a good quality ball. I’ve had the same balls for about 2+ years now and they still play quite well with only a minimal drop in pressure.The only real downside is that the first session of two can feel quite firm on the arm and it doesn’t sound the same as a regular pressurised ball, but over time I genuinely couldn’t tell a difference.

Great balls. Right out of the box they are a bit heavy and hard and don't inspire much confidence. They become softer after half an hour or so of playing and from then on are great. They don't fluff up easily and maintain their bounce just fine. I can't comment on their longevity yet as I have had them for a couple of weeks only, but so far so good.Much better value than other balls due to their durability. You would be doing your wallet and the planet a favour by buying these!

I bought two boxes back in August and I’m still using the first set (playing 3 sets once weekly). They’ve definitely lost their fizz but still surprisingly useful for an average player at this time of year. The only problem is that their persistence favours the style of play of my main tennis partner who slices everything whereas I do better with new balls!

Fantastic tennis balls, especially for those who don't play as often/consistently as they'd like.The great thing about these is they aren't pressurised, so they won't go flat after the first hit, even if you keep them used in your bag for a few weeks.
