So far we really like it! We need to buy another since this one is short, but we are pleasantly surprised with how well this hose works. There's no complaint here on leaks. It does drip very slightly but our regular hose was much worse, a constant leak ( we have very hard water) so we think this is a great change!

Ex Output:
positive

Shipping was late box came open and missing pieces. Very bad experience. Came dirty and a stain on umbrella, not balanced at all so if you dont get weights it will not stand at all.

negative
