• Ordered early in the morning (~ 4AM) and they arrived the same day although they did arrive in two (2) separate shipments. I think as they were coming from actual brick-and-mortar stores they did not have full stock at one as I ordered eight (8) of them • Already had the same brand but without the Co2 and 10-year battery. Got tired of hearing the older ones seemingly start beeping soon after the batteries were replaced. As they were over 10 years old decided it was time to replace
