Top spray, durability flop

It might be a nice product, very very fine spray!
But unfortunately, the article believes that greater use is not enough.
I have the article about 14 days and use this day for orchids and bonsai.
50 sprays a day.
After 700 puffs of pump sprayer pulled with full air condition.
The problem worsened noticeably.
The only reason can still be a faulty connection between the hose and head!

Would be a better life if I could recommend the product highly.
