my son likes it.
Excellent tool to increase swimming strokes. Yet, if you have never used a snorkel you should make sure you keep to the shallower end of the pool for a quick response stand-up on the pool floor. Once you have it down (i.e. head position) you will enjoy the fact that you can increase the number of laps you usually do during a routine. Excellent if you want to build strength, stamina, and speed into your swim drill.
I have been swimming with this snorkel for 3 months and I love it. I would recommend the extra "cap" be purchased as well. I have not had any issue with water entering the snorkel. This snorkel has allowed me to continue swimming despite a cervical disc problem. I won't lap swim without one ever again!
It has a little leaking while swimming but it helps to keep your mouth watery after 1 hr so you don't stop for a break...
So far I've had a problem keeping water out. Purchased clip from Finis for top to help keep water out but it didn't seal correctly. Unless you are a very accomplished swimmer you should order the more upright version of this snorkel. Concept is great if you have issues with breathing when you swim.
The snorkel only works if you have perfect head position and you maintain that position for the duration of the swim. Second, even if you have perfect head position you need to swim in a pool with no waves/chop. If you swim on a masters team with lots of waves and chop then you will constantly be fighting water in the snorkel. Get the regular adult snorkel not the freestyle snorkel it sits higher out of the water.I have been a masters swimmer for many years, and compete regularly. I am currently reworking my freestyle stroke to increase my speed and efficiency, and my coach recommended that I get this snorkel. He said that using a snorkel will take my breathing out of the new stroke and would make it easier to focus on just my head position and new arm stroke. I used the snorkel and can't seem to go more than 2 laps without too much water building up in the tube. I asked a coach to watch me swim with the snorkel and he said that my head position looks great and was pretty consistent, but the snorkel opening only sits about 1 inch above the water. So any waves in the pool or any small bobbing of the head and water will come in through the opening. On the positive side, it worked perfectly on flip turns. I had ZERO water come in even after 4-5 fly kicks off the wall, but it does want to shift to one side of your head as you rotate from your back to stomach during the fly kicks off the wall. I finally went out and bought the regular adult snorkel. This one sits much higher out of the water and works great for me. Unfortunately it does not work as well on flip turns. After my flip turn while I am shifting from back to stomach during my fly kicks the snorkel twists to one side of my head. So you you need to either stop and correct the position or correct it with a quick flip of your hand during your recovery stroke while swimming. I decided that it was easier not doing a flip turn, but rather stopping and pushing off the wall. I hope this helps.
