I currently shoot the TR React 1 on my Mathews. I love the concept and the sight isn't overly heavy like it looks. However, I've had issues with the downrange accuracy with the react technology. Shoots great out to about 40, but after that the react technology doesn't keep up with my arrow drop. This isn't due to the sight as a whole, but rather the helix fletching on my arrows I do believe. With that being said I'm looking to switch sights year, and would give you a helluva deal on a year old react 1. I would keep the sight, but am really leaning towards trying the TR React V5 this year.
