I’ll try that next time, although I’ve never felt like my sensor seemed wiggly or loose. Usually I push straight into the flesh to get good adhesion and then I push the button. The 4 sensors that failed early were on upper arm (2) and belly/side ish (2). Three of them had travelled with me to Kauai as spares, going through airport X-ray several times as well as the agricultural X-ray they use there…maybe that screwed them up?
Last night I gave up on my G6 sensor (at 9 1/2 days) and decided to start a new one. Used one of the replacements recently received from Dexcom, to take the possibility of a bad lot out of the equation. Did not have time to presoak but have been getting good accuracy today, 14 hours after starting it.
In response to @emp00 above, I used (1) skintac on my alcohol scrubbed skin, overtaped (home made using Grif tape) using more skintac with a tight overlap up the edges of the sensor base. This is an upper arm installation, pretty standard for me in terms of no bleeding, no pain, around the back a bit to minimize inadvertent bumping.
