I had high hopes this would ease my blocked sinuses but it didn't really make a difference. The applicator is a nozzle which fits comfortably upright in the nose, but you have to press down on tabs on the sides of it to squirt the liquid out and I found it awkward as it was quite stiff. You gently blow your nose then squirt the liquid up into each nostril. Yoo quickly get used to this and it's comfortable - it doesn't sting, and you get a slight smell of honey. Sadly I didn't notice it making any difference to my congestion.
