The most simply named smart ring possible got less than favourable reviews on its release – in fact it was dubbed one of the 'worst wearables in history'. We think that's a little unfair - we've seen worse.
Crowdfunded on Kickstarter by makers Logbar, the Ring uses gesture controls to perform numerous useful tasks like controlling your smart home gadgets to some not-so-useful ones, like controlling your smartphone (when it's right in front of you).
Manufacturing and testing delays followed by a less-than-perfect product meant that backers weren't happy with the final product but we have to admire the ambition of the makers and we reckon it won't be the last we hear from them.
