Very good product to push it's physical limit. I recommend this product to everyone who is looking to improve cardio and practice swimming strokes.
Very happy with my sw tether travel pack. Easy to use and the best swim workout ever.
Works as advertised. Once you get it dialed in, as far as tether length goes, you'll be all set to swim to your hearts content.
Nearly three years in and I continue to use my Swim Tether regularly. Since my original purchase, I've ordered a traveling swim tether pack that I love. Love it and the selection of products I can order to take my swimming to the next level!
