Are these patches waterproof?

they are water resistant…which is plenty as the sensors themselves are all waterproof…they are great for swimming and showering and sports, yoga, sweating etc – that’s where they work best and are purpose designed to withstand swimming and the impact of water causing sensors to fall off___ they are designed by a swimmer and also have the option to leave middle section non-stick so that they don't stick to the sensor itself...making it easy to change patches and sensors as needed

How many patches come on one order?

Hi, there are 20 patches in a pack and they last for 7 to 14 days - they will cost about $1/week and will keep your sensor 100% stuck on for the duration. Such a good purchase.

Will it last for all 14 days?!?

Hi Tim...they have a non-stick backing section that allows easy changing without sticking to the sensor. I've found they can last 7 to 14 days depending on skin condition and the application process. I've never lost a sensor since wearing then and I tend to change roughly 7 to 10 days.

I needed same one told me what meter i used for this sensor

Hi this product is only a patch to cover the sensor from fall down by accident. If you want a sensor you have to buy it separate with its own Metere it called libre
