I haven't used a nasal decongestant before so this was my first time. It is easy to use and cleared my nose. Not so sure about having two packs in one, there was not single pack available. I only used one but a two pack would be good for a couple or a family.

Gives immediate relief of sinus congestion
3 June 2023

I bought this nasal spray for my recurring sinus problems and also for members of my family who suffer from the same issues. The product works very well and gave us all almost immediate relief. The package arrived promptly and in perfect condition. The price was also excellent.

This really works but it cannot be used all the time. A pity.

The best nasal spray I’ve tried easily
17 June 2022

The best nasal spray in the market, requires far less usage than dimetapp and Sudafed, much longer lasting and doesn’t clog you up after a week, cheaper in a twin pack than it’s competitors also
