I’m generally very pleased with these tees and find the performance as described. They do fly when you hit your ball, so it’s possible to lose them, but more importantly, the edges upon which the ball sits do wear making it difficult to balance the ball on the tee. Overall, I like the tees and will continue to use them. I hate that people leave the “free” tees all over the course, so I feel these tees are more environmentally friendly as we try to keep them.
