My review of the Laser Trainer is that it is fantastic. I have used this with the third eye stroke trainer that he includes, and it will help you correct stroke flaws and straighten out your stroke even more. It is definitely worth the money and can be used on any shot. There are other laser trainers on the market but this one is the best imo. This trainer will benefit all levels of players. A fantastic product along with Joe's great customer service. Charles
