The business side was all professional and the delivery was so quick and the product was as describer they were blue in colour and round with a split down the middle which allowed you to slip them over a standard Pool Hose and yes they allowed the house to be more buoyant and float just what I wanted ,
Even thought they were a Zodiac brand I used them very successfully on another brand Pool Cleaner.
And best of all they are genuine Zodiac parts and the cheapest on the Net by far , highly recommended. Raymond.
