Moisture gets under it really easy also.

A bigger problem I ran into is that when I would work out or be out in the heat it would build up moisture inside the case

Moisture gets trapped underneath.

There was constantly bubbles in it and it trapped moisture

The one flaw as the title mentions is if your watch is exposed to water, like mine is, it is going to trap the moisture inside the case on top of the watch face

The only negative issue with this cover is moisture gets trapped between the watch and the cover

As soon as I start working out, the moisture gets underneath the cover & completely disables the touch screen function

I have this one star because moisture will get trapped under it and mess with the watch.

Sometimes requires removal to clean when moisture gets trapped beneath, but easy to do.

Also, you wont be able to exercise with it as moisture makes the watch unusable.

At first it works good until moisture gets in and then my watch won’t work

If you exercise with it the screen clouds up and you defiitely can't see your watch until you remove it and expel the moisture.

Do get moisture from sweat and rain in between the face and cover but not hard to clean out

Moisture gets trapped as others have mentioned.

The only negative is that the moisture gets trapped underneath

This moisture prevents the touch feature on your Apple Watch, super annoying

But, it traps moisture and needs to be removed frequently for cleaning.

Even with extra care a little moisture seemed to creep in

But a big but, if you sweat around the wrist, moisture / sweat does creep in the case - specially on the sides

As others mentioned, it traps moisture, but I knew that going into it, and it is inherent to the design.

I like t a lot.

n’t take away the beauty or color of the Apple Watch and doesn’t add any weight

n’t interfere with the functionality.

n’t think I should be wearing a watch at all I destroy everything on my third

n’t clean
