[This review was collected as part of a promotion.] Let me say this first: I love when this product works properly. It’s amazing. However, I’ve had these only a month, and one of them doesn’t fully stay on the backing of the splash guard. So frustrating.

Love that I can use
[This review was collected as part of a promotion.] Love that I can use these anywhere and not have to be attached to any cords. They are a bit bulky and there are times when it is tough to get the right suction. But overall, great for any BF mom that is needing to do some multitasking.
