We got this for our daughter who will be a senior this coming school year. She was shooting 46% from the 3 line when she went into a slump, i always noticed the ball twisting on her release but at 46% i just chose to not bug her. Well by years end she slipped to 35%, with the ball missing right. We tried to correct it mentally but it always came back. So we bought the J strap and after just 3 45 minute seasons the spin is almost completely gone. By the time season starts we expect that 46 % to return. AND THEN SOME. This product works PERIOD

The J strap does not work as well as advertised. I'm better off just not wearing it at all and just focusing on keeping my off hand from flicking the ball.

The J-Strap does everything as advertised. If your shooter will use this for a period of time it will definitely eliminate the off hand from their shot. I have used this with three kids since ordering and all three have made significant improvements. Two of the three have progressed past the point of needing the strap and the other one is close. Highly recommend this product at a younger age so they get off to the correct fundamentals early.

Good product, seeing results already with my 11 year old daughter. She is starting to loose her thumbing issue.

Performed as advertised, provided the strap is on properly and fits snugly enough to restrict the non-dominant hand release. Our players (HS Freshmen) who have thumbing issues have really benefited. We had no issue with the non-dominant fingers becoming involved per the previous review.

Disappointed, the strap helps with the thumb, but does not prevent the boys from using there first three fingers of guide hand to help shoot the ball, the boys I am working with our 10 to 12 years old, I have been coaching 20 years, college ,high school and youths, I was really hoping this would help, but it looks lik push-ups and pull-ups will work better and give strength
Thanks for trying though
