It was absolutely impossible to connect it to the phone; since you sell second-hand goods at Alza, it would be good to check whether the previous owner had unpaired it correctly

Resolved by complaint. They probably have a QC problem and the product needs to be developed further. I'll wait for the next generation.
The ring could not be paired with the phone

In any case, it does not have a measurement of blood oxygen saturation. There are several threads on reddit that deal with this issue. He doesn't. The manufacturer itself kindly states this information and ALZA just took over (I don't blame them). I will be returning for that reason, an important piece of information for me
does not have an oximeter

I’m writing this review after more than two years of use; I only take it off my finger when I’m charging it. I don't understand these reviews saying it lasts a month and so on; I doubt I was just lucky. I am extremely satisfied with the product.
collects and analyses data effectively
A nice app – free
After two years, the battery life has dropped to a maximum of two days

There is probably no point in listing the pros, because there is only one negative that will discourage you from buying the ring. I bought the ring for my wife. After about 2 months from the date of purchase it was charged every 2 days and after 3 months it died, not even one day. Ring returned to Alza. Now I see that in the meantime the complaint rate has risen to almost 20%. This is certainly not a product that deserves attention. I myself have a Samsung ring, with regard to the ownership of the phone. Problem-free ring, which I recommend to everyone who owns a Samsung phone.

Completely dysfunctional. Always disconnecting from the mobile, plus the batteries get inflated quite often.
