I purchased the citronella candle a few weeks ago, but we didn't use it until last evening...we had a physically distancing gathering with 4 people on our back deck. We were attacked by mosquitos until I brought out my candle, and they all but disappeared...only one guest got one bite. To be honest, I was amazed at how well the candle worked to keep the mosquitos away, and we sat outside well into dusk. The candle also burned evenly, it hardly made a dent even after 3 hours, and it didn't give off a strong smell, it's a gentle lemon fragrance.
