I had never tried a similar product before since I didn't swim very often. I mainly bought it for strengthening due to a shoulder injury, and I can say it does a very good job.

The fingers hurt after an hour, they don't tie securely, they are hard and uncomfortable. I will not buy them again, spend 15 euros more and get something better that will be functional and comfortable for years.

They are small, the tires are not convenient, especially when you do a lot of meters. Of course, you get what you pay for
