This is a follow up to a review i've left earlier detailing the below

I would genuinely give less star's if i could, where do i begin?
The ring was great intuitive and hard wearing, what ultrahuman don't tell you is that they have a manufacturing issue for a defective battery so after you've purchased this lovely shiny expensive ring which is a bit more than their competitors you'll be riddled with battery drainage issues.
It's not a mild case either it really is severe battery drainage issues. They refuse to take responsibility for this and decided it was perfectly fine not to replace my really really expensive ring. They do not care about the aftersales of their products.
The customer care teams fob you off with excuses and take their time in responding to things that are simple and straight forward.
I would not consider or recommend this brand at all. if you want a smart ring genuinely do your research and consider a cheaper option.
The loops I have had to go through to get a refund for the warranty i paid and the plug in is beyond hard work. I can't express how disappointed I am with a brand that had good youtube reviews. I wouldn't consider a smart ring again going forward ultrahuman has completely ruined the experience for me.

I have emailed the email you've provided and it's bounced back to say it doesn't exist? What a joke of a company you truly are.
