Now that we've had several months of experience with these tees, they are the only ones my wife and I will ever use. We bought them after I saw a friend using one, and he said he had been playing with the same tee for months and loved it. We do as well--easy to insert, consistent tee heights, colors make them easy to find on the tee box (tee is usually behind the golfer when it comes out, as the website indicates), and they pay for themselves by avoiding the fairly frequent expense of replacing wooden tees. A great product from people who exhibit the values that made this country great, but which are unfortunately quickly disappearing. Thanks for the moving tribute to your Dad.
