Does anyone know of an affordable, long-lasting diffuser?

I usually keep a diffuser in the bathroom, but the one I bought at the supermarket seems to have completely faded away in less than 10 days.

It's strange, maybe I used the stick too much.

Does anyone know of a long-lasting diffuser with good value for money?

I'm thinking of buying it online.

If you've used it, please give me a recommendation~^^
