Score: 85/100
Sixmou i3
Score: 53/100Rankings

The AKASO Brave 4 offers 4K video, dual batteries and a versatile accessory kit at a very low price, targeting budget-conscious adventurers. While it provides solid image quality and waterproof capability, it lacks a front screen, has modest audio performance and limited battery endurance.

The Sixmou i3 is an ultra-compact, thumb-sized action camera that delivers 4K video, deep waterproof capability with its case, and versatile magnetic mounting. Its tiny size and pass-through charging make it ideal for discreet POV capture, though it lacks a built-in display and depends on a smartphone app.
