It looks like Chris From The 740 is disappointed with the  Hexion Tech Seeker Red Dot from Strike Industries. This is a compact and modular open reflex sight for pistols. It features three optional shrouds (small, medium, and large) for enhanced reticle visibility and protection. With 8 brightness settings, 3 reticles, and 4 modes, the Seeker offers versatility and ease of use. It fits various handgun platforms, uses a CR2025 battery with up to 30k hours of life, and includes a battery-saving function. The Seeker is claimed to be highly impact-resistant and uses an efficient micro-LED for years of maintenance-free use.
