Okay, so I've been using the Libre 2 for about a year now, and let me tell you - losing sensors because they get snagged on clothes is THE WORST. These SUNMON covers? Total lifesaver.
The waterproof feature is legit - I've showered, swam, and even did hot yoga (so much sweat!) without any issues. The glue-free center is genius because it doesn't mess with the sensor's original adhesive.
I got the black ones (they look kinda cool tbh) and the material feels really soft against my skin. No itching or irritation, which is huge for me since I have sensitive skin.
Pro tip: The package comes with FORTY covers! That's like... a year's supply for me. And they actually last the full 10-14 days as advertised. No more waking up to find half-peeled patches like some other brands.
The only tiny thing - they're a bit larger than expected, but honestly that just means better protection. My sensors haven't gotten caught on anything since using these.
Seriously, if you use Libre sensors, just get these. Save yourself the headache (and money) of replacing lost sensors!
