Long wait for sure, we just had our coldest February in history. The Zepp is great, through the app it shows you if your over or under the plane "top". I'm 60 and my swing speed for driver was down to about 75. After working with the Zepp and bringing my plane to 0 or -5 so I'm not casting any more my driver is up to 85-90. I hit balls a couple times a week at a golf dome and can tell my ball striking has improved a lot. Another thing it shows is your tempo, mine at the beginning was 2-1. It's sup to be 3-1 so after slowing my tempo I'm starting to improve all my positions. My son live in South Carolina and plays to a 3, I don't expect to beat him but I'm hoping next time we play to shock him with a better swing.
