What diffuser product do you use?

What kind of diffusers/air fresheners does everyone use?

It's nice to smell good when you come home, isn't it?

So even though I put diffusers all over the house, the scent isn't coming through well.

I placed one in every room, and also put one in the living room and shoe cabinet, but the scent is weak.

What could be the problem? Is there a diffuser out there that has a strong scent and works well?

Please recommend a good product!
