Very bright and easy to use underwater. The twist-on feature is convenient, but it was a bit harder to operate with thick gloves. Still, lasted me the whole night dive with no issues.

Devika Nair –
I really appreciate the lightweight design—didn’t even feel tired after holding it for a long dive. The mask strap is a great idea, but I wish it was a bit more adjustable for my smaller mask.
