FebrezePLUG, Gain Original, Starter Kit & (2) .87 fl. oz. Refills

The oil scent is strong by itself without power. I have it plugged up to an Alexa smart plug so that I can control when the oil is activated which seems to make the oil last even longer.

Great smell of Gain, the smell in the beginning is a little strong which I love that. Like I said if you love the sent you’ll love this scent . I don’t understand ppl that say worst smell, does the job plug it in and let the scent do it’s job

I should have trusted the few reviewers who mentioned that the smell is awful... it's very strong and smells like toilets in airports! I have the plug in the basement, about 300 sf, the smell was so strong after 2 days that I removed 1 bottle and only kept the blue one, still the smell is too strong (and really, there is nothing fresh about it, chemicals at best).Now I have the bottle on the floor, and unplugged, it's much better.I will just keep it unplug and swap for another brand once the bottles are empty, argh.

I use this in my RV and it always has a inviting fresh smell. Highly recommend

Deff has a great smell and lasts longer than other kinds
