Fantastic

In my opinion diffusers from CAHM are the best I have ever purchased (and I have really purchased a lot including luxury brands). The scents are beautiful and the aroma lasts throughout the bottle usage

Beautiful summer fragrance!!!

I absolutely love the Indian summer smell in my new reed diffuser. It replaced my Christmas spiced orange diffuser and has a fruity and citrus smell of warm summer nights! My living room gets many compliments on its fragrance!

Smells divine

Just love this, smells divine and is long lasting. Bought hand/body wash and lotion. Expensive so use it as a treat. Packaging ie glass bottles are lovely

Gorgeous long-lasting scents

The wax melt sample box is brimming with gorgeous scents and is a brilliant way to try out scents I’ve then gone on to buy in larger sizes. Excellent value for money as you get loads of samples, and its nice to have different scents for different times of the year/moods etc
I love all of CAHM’s products and will always come back for more for gifts and lovely treats for myself :)

Everyone comments on this

What a delightful fragrance, it fills my hallway with a soothing scent. Wasn’t sure I’d like the black Reeds but they look really striking. Love it!

Lovely gift set

I bought this as a gift but I also bought a burner for myself which I love! I'd previously bought the wax melts whilst on holiday in Scotland and loved them so much I did an online order.
