Excellent device for lap swimmers
352650
I purchased this counter on the 9th of July 2014 and have found it absolutely reliable over the past three years.  I swim every other day for about four months of the year (summer/outside pool) for over one mile (55 laps in my pool), and I find the only time I've had any problem is when I mistakenly missed hitting the button (hey, it can happen!) -- in other words a human problem.  It was *relatively* expensive then, but the same price as now (2017).  But given its three years of reliable service one cannot complain.

I only swim to take some stress off my legs.  This device makes swimming tolerable.  Great product!  Beware that you need to convert iTunes format music but it's easy to do.

Desperately wanted music for my kickboard and freestyle lap swimming - got it! I had a running injury about two months ago and switched to lap swimming because I could not put weight on my hip for about 3 months. Lap swimming/kickboard alternation. The one thing I desperately missed was MUSIC. Music kept my running going - never ran without it. After much research, decided upon the iPod shuffle waterproofed by Underwater Audio. It's fantastic to have music in the water. I noticed I swim more vigorously, and enjoy the time in the pool much more. I stay longer - as I did when I listened to music running. So, in the package: the iPod Shuffle, earbuds for water use, a floatie to attach to the shuffle (in case I use it someplace less safe than a pool), and VASELINE tube. The earbuds have a short cord, which means that their cord does not get in the way of your stroke or any thing else in the water. The iPod shuffle is easy to use, hold hundreds of songs, connects and loads via iTunes, so that's easy. The earbuds come with special tips that hold better in the ear in the water, and these special tips come in two sizes. This is good. I have discovered that my ear canals are each a different size - so I can custom configure. The vaseline is place around the outer edge of the bud before you place it in your ear canal. The vaseline helps create a seal, especially when you hit the water for head emersion. On the first day, I experimented and found my most comfortable position of earbud rather quickly. With your head underwater, the earbuds tend to sound best, not that they sound bad with head above water. I'm switching between kickboard laps and freestyle - so my head is in and out. Instructions show clipping the TINY iPod shuffle to your goggles. I clip it to the shoulder strap of my swimsuit (female) and it is convenient and secure. If you're a guy, I imagine you'll have to use goggle strap. The unit also comes with a longer earbud cord that you can use if you want to lengthen short strap - I imagine that a guy could use this to have enough earbud lead to attach the iPod to the waistband of their swim trunks. The note from Underwater Audio says the buttons of the shuffle may be stiff from waterproofing, but I haven't found them bothersome. It's weird to have an electronic device in the water, underwater...but I couldn't be happier. Thrilled I invested in music access for my workouts in the pool. So happy with Underwater Audio's service and this product.

I recently started swimming laps for health reasons and my eyes  were having  trouble with the chlorine content in the pool.  Your swim goggles (Aegend)  came highly recommend by Amazon, so I decided to give them a try.  The day they arrived I raced off to the pool to try them out.  They worked out perfectly.  With the easy adjustment straps, I had them on my head in record time and started my laps.  I was amazed with the clarity of the lens.  I would highly recommend these goggles to any lap swimmers / or even those individuals who just want protection for their eyes in recreational swimming.

This is a very nice aid for swimming freestyle and breaststroke. I haven't tried it on butterfly, and it poses no trouble with backstroke. The rubber for the mouthpiece is soft and there is no offending taste. I would recommend this to a friend.

This little lap counter is great. Once you get used to having something on your finger, it allows you to enjoy the swim without stressing about what lap you're on.

My regret about this product is that I didn't go for the more expensive model. I thought all I needed or wanted was the counter. But now that I've got the product, I wish I'd gone for the one with a stop-watch. At the time I didn't realize I'd want that, but now that I'm using this all the time, I wish it had the timer.

Spend the extra and get a more full featured device!

I'm one of those people who needs music to exercise, and this gadget has revolutionized my workout by allowing me to add lap swimming on a consistent basis.  It comes with different-sized plugs to get a good fit, and the sound is great as long as I keep my swim cap over my ears.  The buttons are a little stiff due to the waterproofing, but I haven't found that to be a problem.  I love it,and people at the pool are always asking where they can find one.  Thank you!

I wear shoe size 8.5 and the yellow medium fit just right. I don't get any traction from my feet alone, so I wear these so I can move some water. They give my legs a better workout when swimming laps. Highly recommended for all lap swimmers. Trained, competitive swimmers don't need them, but for someone like me, who just swims to stay in shape, they are great.

Very comfortable for lap swimming. I do use Swedes for competition. These fit me better than the Speedo equivalent.

I haven't been swimming as much as I used to. I primarily swim as an amateur (age group) triathlete and for fitness. I got a little burned out in the last year and haven't been swimming as much so I thought this might help re-invigorate my swimming and also make it easier for me when swimming at my local neighborhood pool that doesn't have a pace clock.

The unit has several modes and I followed their recommended workouts the first time using it. But let me back up a bit and talk about the functionality and use. I tried it first under my goggle strap, but after it popped out on three different occasions when pushing off from the wall or turning at the wall, I gave up and put it under my cap. I thought it was be uncomfortable, but I had no issues and found that it was quite comfortable. I hardly noticed it under my cap behind my ear.

In terms of the buttons and display, I found it was easy to read (though of course, to change modes or timing, I had to take it out from under my cap). I wish the buttons were labeled with something little labels even "power" or "mode" or something. I had a cheat sheet with me that I made and had put in a little baggie to keep by the side of the pool and I was glad I had it because even though I fiddled with it quite a bit before my workout, I found I kept forgetting which button did which. By the end of the workout I was fine, but anyone who has worked out hard knows that sometimes "workout brain" can occur!

I did two of their suggested applications with it on my first time out. First I set it in Mode 1 to beep for each stroke. I found their recommended starting points to be CRAZY fast. Clearly I need to work on my stroke rate! After finding my "ideal" stroke rate (which was closer to their super slow distance per stroke rate) I did some 50's at that rate working on increasing my effort but keeping the same rate.

Next, I used the Tempo Trainer for what I really got it for, which is timing my intervals. I originally though I would probably just set it to my pace time and go from there, but the instruction book gave the idea to do 100's with the timer beeping at each 25 so try to keep an even pace. This was great and probably what I'll use it for the most.

Overall, I found it very handy for trying out some new workouts and working on my stroke cadence as well as pacing. It's very comfortable and easy to wear. I can't speak to the longevity issues others have complained about, but I can perhaps update my review if I have issues.

Ordered the shuffle and the better waterproof headphones together, but received one day apart. I definitely recommend getting the better swimbuds headphones and not the included ones. The iPod shuffle has been a game changer for my lap swimming, and I absolutely love listening to podcasts and music while grinding out a workout including sprints and flip turns without coming out of my ears. The buttons are a little sticky at first (which they talk about in the documentation and is normal due to the waterproofing process), but Underwater Audio was very responsive to my question and offered to replace it if necessary. I feel confident about the 2 year warranty if needed and plan to put a lot of miles on it. Highly recommend this purchase.

So far so good.  I had trouble loading the music and I called their customer service.  This lovely lady answered the phone and ever so patiently walked me through converting my files.  Once converted, the install was easy.  The sound quality is great, love the shuffle feature and easy to use volume controls.  I highly recommend this products to all lap swimmers.  Time just flies by when listening to good tunes!

Excellent flotation device.  Allows my daughter to "swim" freely with confidence.  She used it both in the pool and in the ocean when we went snorkeling.  She was unsinkable and it was great to have her snorkeling with us.

These really work like they say they do - including for breast stroke! Also has really helped improve my stroke - if you use these for a few laps, then go back to normal swimming - you'll be shocked at how you can feel the difference! These are especially useful to me, as I traditionally have a bad habit of using my upper body much more than my lower body when doing laps. These are helping to rectify that bad habit.

Totally worth the investment! Size is great too - not as big as normal swim fins, fit very well in my small swim-equipment backpack.

I've used the Diver for lap swimming. I used a waterproof ipod previously until it quit. I've found this MP3 player to be very usable. It is easy to load with your media, my choice is audio books. Since I use iTunes I had to find out how to convert the media files to MP3 but that is easy. The controls are large and can be reached while clipped to goggles. The sound is very good come from the earbuds. As with all waterproof earbuds I've ever used, they wash out of my ears from time to time. I've tried various sizes and it is still a problem. Overall, it is a good product, seems well built, great value.

I've been swimming for 5 decades- competition and now for exercise. There has never been much in the way of entertainment available for this beyond counting laps, strokes, tiles... Had a Sony Walkman in a bag once but it was WAY too bulky. At Xmas I decided to try a waterproof MP3 player- Speedo or Finis??? and finally opted for the Speedo Aquabeat LZR. It delivered music but was a constant nuisance. It requires a tight earplug seal because any water in the ear blocks the sound. I found that the sound would cut out of one or the other ear unpredictably because of this. It has semirigid ear loops to keep it in place and these don't adjust. After nearly every lap I found myself readjusting the angle of the earpieces to make them work- one or the other side would cut out. Finally I tried putting a swim cap over the whole thing. This held the earpieces in place but made my ears hurt and exerted enough pressure to turn the unit off in mid-lap. Finally one of the ear loops came off and got lost in the pool, rendering the unit useless. So, time for a change. I bought the SwiMP3. To my delight it worked the first time out. The fidelity of sound is radio-quality (not HD) but it is MUSIC. It is hard to hear when out of the water (earplugs fix that problem) but IT LOVES THE WATER. As soon as your head is in the water the music is loud and clear. It holds tight and rarely requires adjustment. It is stable at speed and with flip turns. The only downside is that you can hear the water rushing by your head- I never really noticed that before. I've had the unit for a month and so far it has held up well. Perhaps Finis will get more acoustic range out of the next model but for now this is infinitely better than the alternatives. I recommend this unit to anyone who swims regularly for exercise.
