Great for large pools
Before I discovered Geobubble™, I sold my clients a film with a round bubble. In small pools, it always suited me in general, except for the resistance to shock chlorination. But I always received bad reviews from owners of larger pools, where the roll length is more than 10m. A wet film of a large size becomes heavy and rubs a lot against the side of the pool. The eight really does not have sharp thin corners, so according to my observations, damage to the side occurs a few years later than with old film.
