I bought it because the price is cheap. Until recently I was using it without complaint. However, I thought that the flow rate should be larger if the diameter is a bit larger, I bought a hose of double the inner diameter 15 mm. Then the flow rate increased beyond imagination. It is good for water conservation and it is a good product for me of indoor preservation because it can store compactly. But will experience unsatisfactory if you experience the current 15 mm pressure? So I reduced it by one. It is a perfect score as a product.
