Mom of the next MN Twin This is the best batting tee. My son received this as a gift when he turned 3 and could already use it then. He is tall for his age, but it adjusts very well and is so sturdy. The rubber base makes it safe for when he misses. His batting has improved and a year later, he still loves it. I would definetly recommend this one over the plastic ones available. If you buy the larger softball sized tballs it's easier to hit and use a big bat for younger ones.
