Dexcom G6

I would give them zero stars if I could. My daughter uses the G6 product and it has not been reliable. If you call - plan on being on hold forever and listening to their crappy computer generated music that I have learned to despise. The billing department is even worse - overcharged my credit card 10X what it should have been and I am still working on getting that fixed.

Bottom Line: No, I would not recommend this to a friend

I am a Medicare/Tricare for Life customer of Dexcom. I use the G6 sensors and transmitter. They are wonderful products. Using the call center that Dexcom routes its calls to is absolutely useless. I tried reordering my supplies, I called Dexcom, was routed overseas, the agent said I did not have a valid Medicare number and to call my doctor's office and get one. The next said I needed a four-day investigation to determine benefits although Dexcom used my Medicare account the month before. My sensor expires in 8 days after that I’ll move to another CGM with USA-based customer service.

Bottom Line: No, I would not recommend this to a friend

If you need assistance, you will be placed on hold for almost ever, stuck listening to commercial after commercial prior to being able to make a choice for the next round of choices and the next hundred commercials. The people are great but the phone option menu lengths and commercials are horrifically long and never-ending.

I updated my operating system about a month ago and it seldom works. If they're gonna sell this product, they should be able to keep up with the operating systems. I do not recommend this.

Length of Use: 3–6 months

Bottom Line: No, I would not recommend this to a friend

The app is useless and rarely connects to the transmitter. The sensor had issues and could not give readings and the receiver was getting readings off and on for two days then stopped altogether. A call to tech support resulted in a snippy response to my issue. Stopped using the device completely. Same issues with the G5 two years ago. I thought the product would have improved by now but the product and customer service are as bad as they were before.

Length of Use: Less than 3 months

My first time using Dexcom, two out of the three applicators I used wouldn't release the sensor. When I called Dexcom customer support, they admitted to having issues with manufacturing. They were willing to mail me two new units if I mailed them the two failed units. However, they only sent me one kit to return two units. When the time came to insert a new sensor using one of the new units they sent me, the sensor or transmitter kept failing by giving me extremely high readings, even after calibrating it several times. When I called customer support this time, I got someone obviously answering from home because there was a dog barking in the background. I felt like she had a hard time understanding the situation. I also had a hard time understanding her and what she was asking me. I eventually just ended the call because it sounded like she put me on hold? Or was dealing with something at home, possibly with her dog? Either way, three failures out of four attempts at using their product. Sounds like Dexcom started out strong then they outsourced and changed their manufacturing and customer support and it looks like they're headed for rock bottom. I just noticed their stock dropped by $35 a share and keeps going down. I'm guessing the bad reviews, bad products, and bad customer support are catching up with them.

I tested my BG using a glucometer while I had the Dexcom G4 on me. If my real BG is 4.0, Dexcom shows 6.3.

This situation is really dangerous. This product has so many failures – like sensor error, not accurate, bad adhesive tape, transmitter fails sometimes, device doesn't read if not closed time for awhile, etc.

I strongly do not recommend this product.

I have experienced problems with the sensor. I get false readings. Yesterday I was awakened by a low blood sugar alarm. I did a finger stick and my blood sugar was 134. I calibrated. It took 3 tries. According to the start point, my bs was 39. Then it happened again about an hour later. This started at about 2 am. Re-calibrated again. Took several tries. Then early in the morning, I got a false high blood sugar reading — my blood sugar was 189. Calibrated AGAIN. No sleep. The same thing happened the next night at 3 am. I have had sensor troubles before and it is always the same lot number 9117. I requested and reported this and I am still getting these sensors. I am a type 1 diabetic and rely on my bs readings. They need to be accurate.

I'm 74, a widow. Installed this myself. It took me about 10 days to figure the G6 out. It is misleading when they mention no fingersticks. On the days you install a new sensor, you will need to do fingersticks because it takes several hours on that day for it to work well. Have patience. I love it!

Been using it for two years, and it’s a very convenient device if only it sticks to the company's claim. Sensors do not last the entire 10 days, I’m changing mine every 7-8 days, good thing is Dexcom will replace your sensor for any reason of a malfunction and the sensor needs changing before it’s time. You will begin getting inaccurate readings, errors, no readings for 30-3 hrs.

I've been using the Dexcom G6 for about 12 months. I used the G5 before that.

The pros? Ten-day sensor life (compared to 7 days with the G5).

The cons?

1. Sleepless nights because of false low readings (yes, Dexcom tells us that to avoid "false lows" we must pick a site on our stomach that will not put pressure on the sensor). Oh, come on! Are we to sleep standing up? (That's rhetorical.)

2. False highs, particularly during the first 48 hours. Again, sleepless nights (yes, I can turn off the alarms but hey, I want reliability, from the end of the 2-hour warm-up session).

3. The 2-hour "warm-up session" for a new sensor should be improved, given that Dexcom informs customers not to rely on the Dexcom readings UNTIL after 24 hours have passed. This must be improved I think so Dexcom has a way to go to satisfy me on the realistic 24–48 hour "warm up" sessions. NOTE: My experience with the older G5 was that it was much more reliable than the G6 after only a 2-hour warm-up.

4. I'm uncertain about product reliability during hypoglycemia. I can't find it anywhere on the Dexcom site. (Rather than telling me I'm "low", or "urgent low", I want to know the readings.) Yep - it's back to finger prick for that answer.
