The spray promises more than it holds. My impression was that it drowned out smells like a "normal" room spray. Although the nozzle atomized but was somehow not really ok as they dripped also. Cigarette smoke (no heavy smoker) was despite ventilate and spray perceive still. A Mini Spray "Ocean scent" from the KIK for 1 fulfilled much better the purpose to remove foul odor, even a whole day. Conclusion: price / performance is not acceptable.
