After my previous Schwimmbrille went to 15 (!) Years broken, do I now firmly with enthusiasm, as dense and well set may be a new product. Crawl (lateral head movements) over longer distances without the side water runs into the glasses or the seat of glasses every few tracks must be corrected - great! The only tiny gripe: I would have liked a slightly clearer indication that the glasses must be ordered in parts (2 corrective lenses + headband) - in the rush of the order I had overlooked that and been amazed over a packet with only 1 lens therein.
