They say share my experience well my experience is so much better that now they sent me the new bandages I would like to recommend to people to leave that little white circle on the sticky side so you have a place to place your finger and center your bandage for placementthis way you will never have to pull off a new sensor if you put the bandage on wrong to replace it it’s a great product customer service. Excellent moneyback guarantee is fantastic but you won’t need it.
