I was a little leery about putting my phone in the water, but this case works fine. No leaks at all after a few weeks in the water.

One thing that could be improved is that you can''t use the touchscreen underwater (using an iPhone). I like to look at my workouts in the pool, but its tough to scroll if I''m underwater.

I am a swim instructor and life guard.  I have to have my phone at the pool in case of emergency.  
I have a Samsung galaxy 2 and it just fits in the case.  
when you unsnap the top, the dry bag unrolls 3 separate drylock zippers.  the triple zip keeps any moisture out of the main pocket.
I have had no issues using my touch screen, making calls (being heard/hearing) and texting.  It actually works pretty great in that aspect.
I have not tried the headphone jack yet.

Most of the time the "touch" feature on my i-pod wouldn''t work through the plastic case.  Was very disappointed, since I had some incredible shots & videos I could''ve taken the last 10 days in the Caribbean.

Works great. Smells funny though.  However, I love listening to music when I swim!

Now I''ll never miss another call while I''m in the pool!  Also great for our men and women in uniform who have difficulty keeping their cell phones out of sand and dirt.

Earlier this summer I fractured my sacrum while mountain biking. I found a water running/aqua jogging routine online that allows me to get an aerobic workout without hurting my back (can''t swim on my stomach because it arches my back). This item has helped to make my time in pool so much more fun and productive. I workout harder to music. Of, course you have to get the headphones.

I am using an older, large iPod with the click wheel because I was little nervous about using my iPhone. There are no worries about it getting wet as evidenced by me using it 4-5 times a week. I would feel completely confidant using my phone, but now I wouldn''t change it because I don''t want to be bothered by phone calls.

Customer service at SwimOutlet.com is excellent!
