Work perfectly, seal tightly, and spray either quite far in a stream, or gently in a mist (how I use it mostly). I use mine for water and an organic pesticide mix (Dr Bronner's peppermint soap and Neem oil mixed with water). No issues yet!
Pros
Quality construction ensures that these bottles will stand up to frequent use and last for years to come
Cons
The bottles may not be suitable for use with vinegar
