Multiple false spikes, long gaps in measurements, and inaccurate readings (I test with finger sticks as well). I get several sensor malfunction warnings, averaging 1 per day. Apparently there is NO meaningful customer support available. Don’t waste your time and money on this product.

I would give this product zero stars if I could. It is a poor product with no customer support. There is a bot, which is totally useless. My product would not sync with my app. Even after multiple attempts. My guess is that sometime soon we will find out that this is like Theranos - a total fraud.

You can only download the app if you have a US Google Store account. No warning of this on the web site. I tried to cancel order almost immediately, but could not reach a real person and they refuse refunds, even on unopened packages. Terrible customer service!

Worse experience ever. I reached out to a chat agent and no help. I cancelled subscription, however another package came and was charged again. BE AWARE! Also, no returns accepted even of its unopened package.

This device was a complete failure. After following all of the procedures by the letter it never worked. Save your $99 dollars and purchase a different brand.

I want to love this product, but it’s left me wanting. I’ve been subscribed since the product hit the market, but multiple sensors in the past several batches failed at start up and never paired. Removing a failed sensor with fresh glue is torture, too. Since customer service is AI, it is days for resolution and there’s no one to speak with—ever. My recent order was lost in the mail—not Stelo’s fault—but the replacement process is now in its second week because of the lack of comms. 50% of the time, it works everytime.

Both sensors in one month kit never activated --"session ended early" error. They were replied correctly and they didn't even warm up before they broke. And the fine print says there is no warranty and no refunds. Buyer beware of any company that doesn't stand behind its products.

I bought a dual pack last fall (2024-08-31) and the first one lasted me three days before it stopped collecting data because I brushed my arm against the edge of a wheelbarrow that I was using to move mulch. The sensor stayed attached to my arm as if nothing had happened but the app notified me that the 'Session Ended Early'. The device is poorly designed in that it bulges above the skin making it very prone to getting caught. Minimally the edge should have a chamfer/bevel to minimize the risk of it getting displaced. The second sensor, which has an expiration date of 2025-07-31, I applied this morning (2025-01-14) and everything was going fine with it doing a 20 minute setup before providing data. Anyway, sometime during the setup the app notified me that the 'Session Ended Early' with no other explanation. What a waste of $99. What a POS!
