The Insta360 Flow has been reviewed, with the device showing great promise but also having major problems. There are different versions of the product, including the Insta360 Flow 2 and the Insta360 Flow 2 Pro, with the latter being described as sturdier and having upgraded tracking. The Flow 2 Pro also has an AI tracker that can work with android phones and offers similar features to the Flow 2 at a lower cost.
