Since I have recently had a very good experience with this device and especially using the "new attachment" I thought I'd start a new thread. I've had one and used it over the past 6-9 months with my learning daughter, mostly on volleys and some forehands. I had personally tried it before and though it was okay. What WAS a pain was having to always having to switch it when changing sides from BH to FH. When I saw on a recent visit to their website that they had a new attachment that allows you to do BHs and FHs and volleys with NO changing I said lets give it a try. I tried it today when hitting with my normal 4.5 hitting buddy, he sorta smirked at me when I put it on. Well was I surprised (so was he), after a rough first 2-3 minues I started really getting into a forehand groove (my wristy and inconsistent shot) and was just hitting solid and deep with top and was very consistent. It took me about 10 minutes to get used to the BH but then I got dialed in there too. My consistency of stroke was what really stood out to me, and I think there is value in upping that by creating improved muscle memory. What was interesting was that when I had tried it before it became uncomfortable after 5 minutes or so. Maybe I had it a bit too tight but today with the new attachment gizmo and having it just a bit looser I hit for about 40 straight minutes, doing lots of drills - it felt so good I did not want to take it off! I really liked being ablie to just hit and use all the strokes and volleys. I think it is a very good tool for grooving strokes thru correct wrist position and repetitive and correct muscle memory - even for a long time 4.5 like myself. I found in my forehand that often I was not laying my wrist back enough on the takeback and then often would break it too much during the forward swing - the WA really helped me correct that. It also kept me on a better forward swing plane and I kept along the swingpath better. I think will use this in my training sessions and especially with my 3.5 daughter.
