I use Skin Grip brand. https://www.amazon.com/dp/B07G9QQJZZ/ref=cm_sw_r_cp_apa_glt_fabc_2E4VQSZ8SVNDC92WW3RD

I have also used and liked Simpatch brand as well. https://www.amazon.com/dp/B07QGX3HJW/ref=cm_sw_r_cp_apa_glt_fabc_68K05JCRZNCHRBXA6JXJ

Sometimes I use them with a shield if I feel like reusing the sensor for longer. It allows you to pull off the overpatch without taking the sensor with it. https://www.amazon.com/dp/B07Z7L1KSM/ref=cm_sw_r_cp_apa_glt_fabc_CZ2A1SK3XB33YYW792V2

I hate the peelz brand. Way too flimsy, ends up sticking to itself and impossible to remove from the shield. The adhesive is also just barely over the size of the original dexcom sticker.

Wearing it on my arm improves the longevity of the adhesive.

In addition, I improve the stickiness to my skin by using adhesive promoter Skin Prep https://www.amazon.com/dp/B000S9KLSY/ref=cm_sw_r_cp_apa_glt_fabc_P66HR47GMKWRG45RBR10?_encoding=UTF8&psc=1

And when its time to take it off, and the adhesive stays stuck to your skin, I use Uni-Solve to remove it. https://www.amazon.com/dp/B00M3IKRFU/ref=cm_sw_r_cp_apa_glt_fabc_HX2GJ35SHKRPCAJCSRB3

Get a shield. Game changer for me.

Apply in the following order: Skin Tac > Sensor > Shield > Overpatch

This allows you to replace a new Overpatch without peeling the Sensors patch. Change out the Overpatch as needed.

Easily wore my last sensor for 25 days before I started receiving errors.

Hi,

did you have issues with the adhesive not sticking or with allergic reactions?

The shield is great for ensuring the sensor stays stuck on. This is the shield from Amazon I use, but any similar one should work. https://www.amazon.com/dp/B07Z7L1KSM?ref_=cm_sw_r_apan_dp_EVPYYW11KP9TJAFRTDM5

I use the free overpatches you can get directly from dexcom. You can order them here. https://dexcom.custhelp.com/app/OverPatchOrderForm

Put on the sensor using skintac to help stick. Lay the shield down on top of the sensor. Apply the overpatch overtop the shield and sensor. Works really great for me.
