OLGA Grapefruit & Mango Reed Diffuser Refill – 180ml Long-Lasting Fragrance Oil – Luxury Scent Refill for Diffuser Bottles – Sweet, Fresh, and Bold Home Aroma

I've had this a year already and it's still smelling lush! It's used in a small porche 3m x 1m, perfect choice as its lasted so long. I had to remove some sticks, only use 4 as it was too overpowering for the small space. Just turned the sticks around for the 3rd time and still there was a little liquid. Defo ordering again.

Amazing scent, lasts for ages and you can actually smell it unlike other diffusers. Really good value for money

Bought this diffuser oil on the back of all the reviews on here and it didn't disappoint.I've got the diffuser in my hallway and it's a lovely scent that you can still smell in other areas of the house.My only niggle is that even though I haven't turned the sticks, the oil has evaporated very quickly, but that could be due to the hot weather that we've had recently..Still highly recommend..

Smells good. First bottle of car air freshener was damaged, but seller was kind enough to replace it quickly.

I was recommended this product, and it’s one of the few diffusers where the scent actually lasts for a long time. I haven’t needed to buy refills for quite a while. The fragrance is beautiful—not overpowering, even though it’s strong—and very refreshing. It works well for all seasons, and I always get compliments on how nice my home smells.

Love the smell , it is quite strong, so makes the whole bathroom smell lovely!

Smells lovely but the scent doesn't last. Quite expensive for a scent that doesn't last.

This bottle is the perfect size for refilling an Olga diffuser. The scent lasts a long time — easily 2–3 weeks, if not longer (until I get nose blind to it!). I use it in my bathroom, and every time I refill, the fragrance drifts all the way down the hallway. Absolutely lovely!
