Once you figure out how to set the time, it's a good, reliable little clock-- until you accidentally brush the timer.
Setting the timer only seems to work when you don't want the timer, and then clearing it never works. The "instructions" say to "double-touch" the Clear button to lock and unlock the buttons, but that also never works as it shoulds. What does "double-touch" mean? The instructions provide no detail. Long touch with a pause in between? Fast double tap? Some weird double brush? No clue, because none of it seems to work.
So did you accidentally set the timer for 99 minutes because you were holding the clock in your hand? Your only reliable option is to crack the device open and remove a battery to reset it.

If you want to be able to set a timer, get a different device. If you just want a waterproof clock... well I'd still recommend a different device but it works okay.

This is one of my favourite purchases that I've made lately. I love having the time and timer right in my shower with me. I was using my Alexa in order to set timers. However it was hard for her to hear me tell her to stop the timer over the sound of my music and the shower. This is great for things like dying your hair, putting on Long lasting conditioner, or Using it to ensure that you are not in the shower or bath too long. That is what my daughter uses it for. By using this clock and timer, she is able to make better use of her time, and also save water in the shower.

Exactly what I was looking for. Easy to use and I'm happy it comes with the wall clip to hang it on. Very satisfied.

I was using this as a shower timer because I lose track of time very easily. The buttons aren't actual buttons, they're just touch sensitive, but they're not actually particularly sensitive so setting the timer is a bit of a pain. My biggest problem, which is probably my own fault, is that it reset the clock most times I used it. I have the bathroom window open and the exhaust fan in when I shower but it may have still been too humid for it to work properly. If you're using it for a different purpose or you mostly take cooler showers this is probably a lot better for you, but if you take hot showers like me this isn't the product for you.

I've had it hanging in my shower for over a month, and it has kept time perfectly. I don't trust suction cups in the shower, so I can't speak for the suction cup that came with it, but it has not been damaged by the humidity at all. I also don't use the timer function. But I am very pleased with is as a basic clock.
