Digital Camera World Verdict

As you might expect for such a tiny device, it is at once brilliant and imperfect. 4K Dolby Vision video output is great, and the discrete wearability is great, but at the same time, the narrower field of view than the predecessor isn't ideal. Nevertheless, this is truly an action camera which can get shots your phone can't and work in ways which verge on the futuristic.

The Insta360 Go series is a tiny thumb-sized camera which can make other action cameras seem positively chunky, and offers genuinely different possibilities for creators.

It can be worn surprisingly discretely on the body – typically the chest thanks to a magnet chest and an accompanying pendant and, in my testing, made capturing personal perspectives impressively easy.

FeaturesWith 4K, the live remote control and smooth app syncing, not to mention Find My, features are extensive★★★★★
DesignOverall, the concept is brilliantly executed given the limitations physics imposes; everything feels robust and the pendant is comfortable★★★★★
PerformanceThe system has some issues in low-light and with image stabilization (the later may be improved with firmware)★★★½☆
ValueBecause of regular savings on premium action cameras which are better in low light, it is difficult to say this is great value unless you need the POV flexibility – in which case there isn't really any competition.★★★★☆
