Great value, lovely scent

Yes, I recommend this

I bought the refill and it is enough to fill up 2 diffusers. It has a natural lavender and woody scent and I find it fills the room (in a good way) much better than many more expensive diffusers I have bought in the past

Fantastic Smell that Lasts

Yes, I recommend this

I stayed at an airbnb and the whole cottage smelt of this fragrance. I loved it so much that on my return I purchase the diffuser from my local branch and the refill. I have since filled 3 containers with the refill with some to spare. The fragrance Calm has a light smell that actually makes me feel less stressed. No wonder this is the most popular fragrance from the M&S selection.

Yes, I recommend this

I absolutely love the Calm diffusers and have them in most rooms but it is extremely difficult to source the refills and the larger diffuser.

Favourite Diffuser scent.

Yes, I recommend this

Love the scent of this diffuser - my favourite. I prefer to buy the refills and use in my favourite containers. Would like the scent sticks to be thicker though.

Lovely scent that goes a long way

Yes, I recommend this

When we bought our house the previous owners left a few of these dotted around and the smell was so calming. Like a spa. We have continued buying the refills for the last 3.5 years. Great value for money. I split a refill across 4 jars and they last really well

Great aroma but the fragrance is not long lasting

Yes, I recommend this

A lovely subtle aroma that is not overpowering. The fragrance is light and pleasant although it doesn’t stay around for too long and I find it necessary to respray frequently which is a little disappointing. However, the fragrance is delightful and one that I buy frequently.

Very weak smell

No, I don't recommend this

Nice enough smell but sooo weak! It’s in a smallish bedroom and I can only smell it if I stand right next to it…too expensive for the quality…disappointing

A Wonderful fragrance.

Yes, I recommend this

Great to have a refill rather than re-buying the Reed diffuser container and reeds every time. This has refilled two large diffusers and one small one, with a little bit left over. A lovely, discreet fragrance that continues to work right to the end of the liquid. A grown-up fragrance with just the right amount of intensity. So many reed diffusers disappoint, but the Apothecary range ticks all the boxes. The only problem I had was accessing this product. It was sold out online and in my local branches for too long. It’s obviously a best seller, for good reason, so Marks should perhaps adjust their stock ordering to fulfill demand.
