The spray attachment for many products does not function properly

Many companies are providing a spray attachment for their products, yet many users find that the spray attachment does not function properly
They are wasting a lot of time trying to make the spray work, still no fluid is being sprayed.
The user will then dismantle the entire spray mechanism hoping it will function properly, yet it does not work.
So to save money and the users time, if the seller cannot find a good quality spray mechanism, it is better not to include it
