Resolution at last

My ring stopped connecting to the phone weeks ago. Luna really puts you through the paces to resolve. Multiple emails, multiple video’s sent, and finally a gentlemen from the company did a teleconference with me and resolved in minutes. The ring is defective and new ring is being sent. This should have been the option weeks ago when I first reached out. He was friendly, knowledgeable, and immediately was able to confirm what I have been telling them in multiple emails over the past 6-8 weeks - the ring is defective.

Skip this, buy the Oura ring instead. The Luna ring has been full of problems. It is difficult to align on the charger, the battery indicator is not accurate, once the battery dies it is hard to reconnect with the app, there are problems with data syncing, and finally it just quit working. Tech support is under staffed with barely an attempt to follow up after multiple attempts for help. My ring hasn’t tracked data for a week and a half and haven’t gotten a resolution. I’ve reached out to their live chat, helpdesk, through facebook messenger, and direct email. It takes days to get a reply, I follow up with all the requested info, and still days later there is no acknowledgement.Update. They sent me a replacement ring. It won’t pair. I’ve reached out to live chat and tell them it won’t pair. They keep telling me to unpair the device. I can’t unpair what has never paired. So I have two Luna rings now that won’t pair. Since live chat only feeds me canned responses, I’ve reached out to the email contact given to me and haven’t had a reply. I’m about to quit complaining and give up on this product. It has never once been able to accurately monitor my basal temperature and predict cycles just fyi. That’s with a year of wearing the first generation ring that worked intermittently. I don’t think it ever worked consistently enough to collect the data.

It took months of back and forth emails and ultimately the issue was only resolved through support on instagram. I’m adding a star back for the only person who was helpful in finally getting me my product. However, I’m still really disappointed and I really wish the team valued and heard their customers. The look and fit of the Luna ring is great. But other than a piece of really expensive jewelry, it fails to deliver in terms of any real health tracking. In fact, most of the stats are completely useless. I’ve laid around all morning and already hit my active calories with an optimal rating by 11 am. Seriously? What’s the point in having a rating when it’s met every day just by doing the bare minimum to survive? The exercises available to track are so limited and unable to be edited. I walked 5km at a pace of 7kmph and it only showed as 2,000 steps? We should be able to input data if it isn’t able to be measured. Not all walks are created equal. Calories and steps are highly inconsistent. I end up defaulting to my Apple Watch which defeats the purpose of buying it entirely. It feels like this ring vastly overpromised and massively underdelivered.

Hi Jerrica, really apologetic you had to go through this. I believe the Support Team has now taken this up at priority and is in touch with you on Instagram.

Terrible Customer Service

I have been attempting to troubleshoot constant issues with customer service for over a month. At first, my ring stopped syncing, then it disconnected and wouldn’t connect to Bluetooth, recently started to import my workouts from Apple Health multiple times for the same workout, and now AGAIN my ring is not syncing. My workout from Apple Watch was imported, but nothing from ring. I have sent a separate email for every single issue and receive the same generic response, “Thank you for contacting us. A member from our team will be reaching out to assist you with your issue.” To this day I still have not received a follow-up email from the FIRST email I sent a month ago. I completely get being a new product and I even stated in my emails that I’d be willing to be patient with firmware updates, but to at least be responsive to issues that arise. It is completely unacceptable. I haven’t even received a reply regarding returning my ring due to all the issues. Maybe later on this can be a quality product. The ring design is better than most and app is user friendly (when it works), but there are way too many glitches now.
