Review: ACTUALLY waterproof!! - I work in aquatics and teach a lot of swim lessons. One of my weaknesses, that hasn’t improved over the years of experience, is time management, so I went looking for a timer/alarm to help. I needed something that was easy to set with wet hands (no teeeeeeny tiny buttons), that counted down, that had a solidly loud alarm (needed to hear it from a few yards away, over moderate noise of indoor pool including kiddos, pool gutter, and HVAC), and ACTUALLY WATERPROOF. Not “water resistant,” not “waterproof - unless submerged” — something I could accidentally drop in the pool, leave for some minutes if needed, and still come out working. I couldn’t find a wristwatch to fit my needs that was low cost and I don’t like watches much anyway (sensory issues). Enter: this timer. After months of daily use, I am happy to share this timer holds up. I do usually have it on the edge of the pool during class, not submerged constantly, but it does frequently submerge for minutes at a time. (I often put it in my pocket while I’m in the pool or accidentally drop it to the bottom.) It lives at the pool, so it doesn’t have a chance to sit somewhere cool and dry when it’s not in use. None of this has deterred it. The buttons are large and easy to read and press. They aren’t very tactile, but the timer does beep every time you press one, so there is confirmation the button actually worked. The alarm itself is loud enough I can hear it anywhere from 15 yards away (on a lower noise day) to 3 yards (noise loud enough I can’t hear myself think). If I and the timer are submerged, I can hear the alarm within at least 5 feet. It manages to be easily audible but does NOT scare or overwhelm me either, which is a huge plus. The one thing that may be of concern to some is the magnet on the back. Being a magnet, it has completely rusted over and a top layer definitely fell away. The magnet DOES still work, just as well as when it arrived. But I know rust stains can be a pain, so that is something to look out for. If and when this guy gives out (or a particularly intense toddler finally manages to crack it), I’ll update this review. For now, it works wonderful and does exactly what I need very well. ETA: Updating to say the timer did fail about two months ago. (I believe it was largely because the 8yo I let regularly borrow it always held it submerged, for 30+ mins at a time.) One and then eventually most of the buttons stopped working. There was a rattling noise from inside the timer also, but this was there before the buttons failed. So I suspect something(s) internal rusted. All this said — it had a great run and I have gladly purchased two more (one for each pool I teach at). But I should probably label mine since I’ve seen other aquatics professionals using the exact same timer recently! 😅
Review: Works Great — Survives a Lot (Until It Doesn’t) - I bought this for my daughter to help limit shower time, especially since we’re on a septic system at our cabin. It works really well and is easy for her to use. This is our third one only because it keeps getting dropped in the tub. Eventually it will break if you drop it enough, but until then it lasts a long time and does exactly what it’s supposed to do.

## Questions & Answers

**Q: Is it Waterploof?**
A: I was wondering the same. I was originally looking for a waterproof timer, but then I saw that this one says it's waterploof and thought that it might be even better. 
Unfortunately I see the seller responded already. It turns out that waterploof means something between waterproof and water resistant. I believe the technical term is water proosistant.

**Q: How do you set the clock?**
A: It's very easy but the "English" instructions are gibberish.  Here is what you really do:

Hold "Clock/Timer" for a few seconds until it beeps to switch to time-setting mode.  When you're done setting the time, press "Clock/Timer" normally to exit clock-setting mode.

In clock-setting mode:
- Press "Start/Stop" to swap between setting the hour and setting the minute.
- Press "1 min" to change the number.  (Or, if you want, you can press "10 min" to skip 10 at once.)
- Press "10 sec" to switch between AM, PM, and military time.

That's it!

**Q: Which battery does it require?**
A: 3V CR2032

**Q: Is the alarm continues until you turn it off? Or does it just beep once and then stop?**
A: If you get the tear drop shaped one, the alarm sounds for 15 seconds and then stops on its own. Which is exactly what I wanted for a shower timer so the kids get a ‘hey it’s time to finish up!’ Without having to step out of the shower and turn a timer off. It’s perfect!

### ⭐⭐⭐⭐ Great Shower Tool
*by D***N on January 23, 2025*

If you have shampoos or other things to time when showering, this is a tool you never thought you needed. But you do. Convenient and absolutely waterproof. Ships without a battery or it would have gotten 5 stars. You’ll need a 2032 battery for it to operate.
