Diamond Golf Tees – Patented Design to Reduce Spin for Long, Straight Drives – Low-Friction Long Tees, Robotically Tested for Ball Spin – USGA Approved Performance

Don't think these really affect my ball flight much at all...still hit it about the same. BUT...they are VERY durable so I can carry ONE tee in my pocket instead of a handful for several rounds! They do EVENTUALLY start getting some knicks and chips and I've actually broken 2. One pack will easily last a once a week golfer for a year or so if I don't lose them!

I’m impurity these Tee’s! I’m hitting the ball farther and straighter than I ever have. My friends are impressed with them also which I have given a few of them one to try.

Felt compelled to write this review because I was highly skeptical when I purchased but these tees definitely add yardage to your drives. I played only 9 holes so far but I prob added 10-15 yards to the drives I hit cleanly... Will come back after playing a bit more because 9 holes is noting much to get a trend. Other reviews are also accurate with regards to the fragility. Broke 2 tees within those 9 holes. So considering only 8 come in a pack this maybe an expensive proposition so will keep an eye out of other brands.

Helped off the tee. Good quality and very durable. Easy to use.

They are ok but nothing helps in golf except practice.

Personally not a fan. They are weak and tough to push into hard ground, they didn’t snap but it’s like pushing a half cooked noodle. Also first hit on every tee so far the front ball retention tip snaps off so I was left with only the two rear tips so ended up leaning it back to hold the ball and that didn’t help it any way.

After seeing an advertisement for these golf tees, I decided to give them a try. I'm someone who struggles with slicing and getting the ball up in the air and off the ground. This tee has helped with both issues immensely. The tee is very durable and I have yet to have one break or bend on me after many uses. The directional arrow helps significantly with flight path if that is also something you struggle with. The only negative thing I can say about these tees and it is a small complaint at that, is that it can be a little tricky to get the ball to stay on the tee when first putting it on there because of the design. Once you do it a few times though, it's easy to get the hang of it. These are worth every penny.

I bought these for my son for Christmas, he loved them

Yes, the item seems to deliver as promised, however it is very expensive compared to other tees.

Great feel on drives.

Premier pack reçu en cadeau, j'étais dubitatif. J'ai dû me rendre à l'évidence, ça marche : un peu plus de longueur mais surtout beaucoup moins de slice au drive. J'ai commandé un autre pack dans une taille inférieure pour terrain dur. Attention il existe des tees semblables beaucoup moins chers que des amis utilisent mais ils sont beaucoup plus fragiles.

Great product. Nearly unbreakable

Great product would highly recommend
