Hi there, thank you for leaving a review for our Reactive Knockdown Self-Resetting Laser Target. We're happy to hear that it has been a helpful tool for training your grip, draw, target acquisition, trigger pull, and first round hit. We apologize for any inconvenience with the targets not working in abundant natural light. Have you tried using the shoebox for practicing under light? That may help with the issue. Thank you for your feedback and happy practicing!
