THE BEST!!
Color: Multicolored 4, Size: 3 Pairs (Pack of 1)
Wish I found these last year! My daughter is on a swim team and had 3 separate episodes of swimmers ear. Bought these and not a single issue, keeps the water out yet she can still hear. Perfect for little ears, the price, and convenient to have extra sets.

Effective and comfortable
Color: Multicolored 2, Size: 3 Pairs (Pack of 1)
Great! I have used Macks silicone Chistmas tree style earplugs for many years, these are more comfortable. They keep ear canal completely dry, never fall out during swimming, and are easy to insert and remove with no discomfort whatever. The left and right orientation makes them easier to adjust in the ear, and there is no (sometimes painful) pop on removal, like standard silicone plugs with a stem. Happy swimmer here.

Didn’t do much for me but the product is made very well
Color: Multicolored 1, Size: 1 pair (Pack of 3)
Maybe it’s just my ears but these didn’t really work for me. They’re made very well, but they really didn’t keep water out of my ears. I swim laps daily and am very sensitive to ear infections from pools. I even wear a swim cap with them. They do stay in place and. I love the little case they come with. I’m sure they’ll work well for other people

these earplug’s work great, I use them when washing my hair, it is so nice not to get water in my ears, these earplugs are comfortable, they come in 3 sizes, each set comes in an individual plastic container, they are marked L and R, I’m so glad they worked so well, I highly recommend them!

Love my mat!
Color: Pink, Style: 1/2 Inch
I’m new to stretching and recovery classes, and there is a lot of floor work. I was using the gym mats, but my knees, lower back, and glutes were hurting from being on the floor. This mat is the perfect thickness and feels wonderful during floor exercises. It gives me the extra cushion I need without being difficult to use. It’s also lightweight, durable, easy to clean, and easy to roll up for transport. The pink makes me smile. That said , the mat makes the classes more enjoyable.
