Some thoughts I had while reading all these...first, it' sometimes "off" happens with your equipment, even if you're not sure it's a real issue, call the company. Dexcom or whoever. I found with Dexcom and Minimed both, they want to know when something goes wrong or even just "weird"with their products so they can work on a solution or more importantly, you may be the lucky person who has the problem first, like before anyone ever experienced it before.. like you may be the first time anyone has ever called them with the issue. I'm pretty sure that's what happem d when my very last sensor came out of the package with the needle already retracted!! About not getting the most out of your G5...could the stick-on-ness, new word there, be a hair issie possibly? Could it be a skin-prep issue? Especially if you're going to attempt getting more than a week from a sensor, I found that skin prep is a big deal. Even more so in warm weather. Someone here suggested to me to try liquid SkinTaq and it's been the answer for me. I use it under the entire thing. Even after the sensor is in, I'll put more SkinTaq on the area where the other adhesive tape will be touching me. I've had zero issues with sticking after I started using SkinTaq. I also make sure I prep the skin well with alcohol just so all oils are removed. Thankfully no sensitivity issues doing this so far!! Another thought I had was having someone help me affix the Dexcom. I wouldn't be able to wear them in my arms without help. I could probably get one in, but it wouldn't be to the back of my arm where I prefer, & would be more likely to get knocked off. Maybe I'm not as flexible as you guys are, but the only place I've ever done it entirely alone is in my stomach & I hate wearing a CGM there. I need the help of the extra hands and eyes. I'd never get my GrifsGrips on without folds without some help either. Especially after applying SkinTaq! (I'm not sure how it's spelled either...maybe it's SkinTac? Tack??... anyhow, it's the liquid and not the wipes. ) Maybe some of this was helpful, but I did want to encourage you to always call the company with any issues just in case it's also new to them! It is alway YDMV with these things!!
