Air fresheners are always going to be a personal choice thing. M&K offer a large range to choose from. I went for the New car and Oud. New car does invoke the new car memories I have of being in people’s new cars . The old one I’m not sure on. Each comes in 100ml bottles, I followed the advice given on the M&K site, spray the liquid on a piece of card and place under the front seat.
Neither scent was overly strong, some others hit you quite badly at first, neither did that. By putting the scent on a piece of card meant the scent was blown around the car. There are fan outlets under the front seats of my car. In terms of longevity, driving daily the scent last all week before it started to fade. So with a couple of sprays for both card a week these should last a fair time . If you were using it a a finishing product before a customer picked up their car, then I would say it would be a nice touch for them. All in all as an air freshener I would recommend them for their longevity. Obviously you need to pick the scent you. But then the range is wide there should be something for most tastes

I ordered the Mango and lemon air fresheners and they smell incredible, my customers love them and keep asking where I got them from

I chose cologne and rich sandalwood . Cologne is maybe the most famous and is very pleasant but sandalwood is top of the top by far. The durability of sandalwood is almost double than any other fragrance .Trust me!!!

They smell so good it's almost addictive using these. Take care when using these because someone is bound to use them more than you lol

I bought New Car and Lime and Mango. Both of them are nice as expected. Last for 7-10 days. Good items:)
