I bought a month's worth of Lingo CGM. The sensor would lose signal CONSTANTLY. Brand new sensor applied; STILL LOSING CONNECTION CONSTANTLY. Email customer service at least a half dozen times-- have gotten ZERO responses. I will not buy this product again. Total waste of money, and risk to my health.

I have had nothing but problems. UPS lost my order so after a while, Lingo was to send me 2 replacement sensors, they sent one instead of 2. The one I received worked for less than 3 hours. I contacted them to send out a replacement for the one that doesn’t work as well as the one, I didn’t receive. I got my box today with only 1 sensor in it. I give up! I am requesting a refund and will try another company. My neighbor got her sensor the same day as I got mine. Hers worked for half a day so she is now dealing with trying to get a replacement or refund as well.

Not a good product. Avoid. Sensor was disconnecting frequently and after 5 days fell off completely. After reconnecting sensor will show very high values. Useless. I got 2 sensors on a deal and I requested refund but support kept sending "tips" and "helpful" messages but no word about refund. Thinking of taking them to court. Previously I was using another manufacturer Sensor without any issues. Lingo was a bit cheaper but it is waste of money.

I have used Lingo GCMs for about four months. During that time, 3 of the 8 sensors failed within a day or two of application. And the company will not refund or work with me to get refunded. They know their products are faulty and have tried to make me provide a ridiculous amount of information just yo replace products that are already not working. The software is great, but if the sensors don’t work, it’s a no go. I’ve used Nutrisense and Freestle Libre as well. Both are far superior to Lingo. Customer service is appalling—it takes them 3 weeks to reply to a help Message, and then, the “help” is performative with all issues going unresolved. Try a different product. This one is awful.

Absolutely dreadful customer service. Ordering system hasn't worked, says try later and been doing that for 3 weeks!!!!! Tried the chatbot waste of time. OK email? No, it bounces Telephone call then? Can't help cuts you off. Try again? I swear the agent was drunk or high. Still no help.

I ordered one month subscription for lingo twice. Each time one of the sensor turned out to be finicky. On my last order the sensor stopped working in less than 24hrs and it said to contact customer service. The customer service is even worst. I sent them an email and after 48 hrs got a response saying apologizes for delay hope and we have addressed your concern. Which didn't make sense since they didn't even read the concern. I don't think I will order anymore product from them and I hope this feedback helps other folks to stop ordering from Lingo.

I found it was not taking any readings during exercise. I used the Lingo CGM a s I was interested in my glucose levels especially on longer training runs. I’m a mature plodder, not an athlete. The sensor and my phone were within 20-30cm. I had no readings at all during these runs. The first and last readings showing were well within normal range, I didn’t feel depleted and I ate at intervals. I cannot believe I was so out of the normal range all the time not to provide a reading. I won’t buy another Lingo CGM again. Waste of money. I wish I had read the reviews beforehand.

The first one I purchased malfunctioned. I requested a replacement. After over a month of back and forth with customer service, I finally received the replacement. The application directions were ok, but I ended up using an online video for instructions. The warm up time was 24 hours. During this time, the device lost connectivity many times and required turn on & off my Bluetooth then restarting the phone. My readings have range 30 to 40 units below what my regular glucose monitor states.
