NIXON SIREN A1311 WHITE Purchased in March 2022. The battery died after about 2 years, and it's been sitting unused since then. I only used it when surfing, so I didn't use it very often. Please check the photos for the condition. It was working fine before the battery died, but I haven't been able to confirm its operation since the battery is dead. It's a good deal for someone who can replace the battery. It comes with the original box and instruction manual. Thank you.
