I tried my new Magic5 goggles this afternoon. I’m really disappointed…they leaked before I’d completed a single 25m length and I had water in both eyes. I had followed all instructions that were included in the box. I adjusted the strap a little, but to no avail. I was in the water for 45 minutes trying everything, but personally they simply do not stay watertight. I had high hopes for these ones as I like to do 45 minutes solid swimming without the need for stopping and emptying the goggles. I have contacted Magic5 accordingly in the hope that they will be able to correct this issue or provide a refund.
