Grip is worse than useless and can't be replaced.
January 30, 2020
I can only assume that the good reviews have come from people who got this and used it once or twice as actual, long-term ownership is a completely different experience. This is *almost* a good product. It does in fact target the specific muscles used in the swing, builds strength, increases flexibility and keeps the club on plane. But it's done in by one fatal flaw that ruins the entire thing. The grip that comes with it is hard, slick, small and will be useless inside a month. I got mine for Christmas and it's already useless. The grip is so cheap that it turns rock hard after only moderate use. Once that happens the product can't be used as anything but a paperweight. The grip can't be changed out for a normal grip and can't be replaced with anything except the same make and model from the manufacturer. If you read some product descriptions on other sites it includes a disclaimer and warning that the grip can't be changed or replaced. RBG omits that CRITICAL information, it should be the first thing listed as it's the most pertinent thing to know for a prospective buyer.
