Question: has anyone had a leakage problem with this product?
Document: This is possibly a worse unit than the loser I had before from Finis. Can't anybody make a good swimming snorkel. But I digress: what I really want to say is don't under any circumstances buy this product unless you want to swallow half your swimming pool. And don't listen to those helpful answers from owners. I asked before I bought about leakage and despite their assurances, my experience was the complete opposite.
The product is good but the color of the product is not the same to picture.I say should always be the same picture that the product is delivered
Used for several months, and works flawlessly! I appreciate that it's adjustable for petite women! Very pleased with this product!
My swimming especially free-style has improved around 89 per cent. Great product! It would be nice if it comes with a nose clip included in the price!
As expected from Speedo, this is a high quality, well designed product that is easy to use. Without having to lift my head out of the water with each stroke to breathe, I tire less quickly and am able to swim 50% more laps.
This is a fantastic product! The ones I used which were on the side of my head always let water into the mask, and I did not like the pressure on my head. This one does not cause any pressure issues, allows me to use my goggles, not a full mask. I use this for swimming laps.
The snorkel slants backward slightly more sharply than the Finis, so I have had to give up my large goggles and go back to the eye-cup type. Also, the instructions say to remove and clean the purge valve, but doesn't say how to do it. But overall an excellent product that has helped my training enormously.
I'm not much of a swimmer! However, the Speedo snorkel works quite well for someone who broke their neck three months ago. The fit was good and one just needs to learn how to breath out through ones nose. For serious lap swimmers who may have similar issues, or who just do not want to breath on one or both sides, I highly recommend this product.
I taped the middle section of the snorkel with clear packaging tape, and that fixed the problem, but I was disappointed in the durability. I am not sure if I just was unlucky with that particular snorkel, or if all Finis snorkels have a durability issue. I hope I get more mileage out of my new Finis snorkel, but only time will tell. (I did not use the Speedo snorkel long enough to see if that one remains reliable over time.)
you must have a good nose plug if you want to actually use this underwater while swimming. noseplug is very needed.
