Mine usually stay on but I have lost one just to not sticking I usually love body boarding but usually for a few hours will have a try out thank youThey also really help with preventing 'knock offs'
I use them all the time tbh. They generally last 14 days for me.
Gonna give them a go as there reasonable priceI used to use Opsite Flexifix, but moved onto these a few months ago as they work out cheaper. Have worked well in the pool for me. I do a 45 minute hard swim twice a week. Not had any issues.
