I do love the smell of gain . But I find the smells holds good enough in the cloths that you do not need the scent booster but if there is a item you are not using fir a while then yes it is good for that . The smell is wonderful as usual

Best scent ever!! Never add a problem about the dissolving in my washing machine, the scent stick very well on the clothes or curtains, no traces at all. Really easy and friendly!

This stuff is great to add extra smell to your laundry. It smells just like Gain, only stronger! I love that it doesn't seem to leave any residue on my clothes, unlike a lot of other in-laundry scent boosters. I love to use this stuff on my bedding, as you climb into a cloud of delightful Gain scent for at least two days after using the scent booster. Added bonus: You can put this into any wax warmer and it melts and makes your whole house smell amazing...
I buy this stuff EVERY time shoppers has it on 2/$10

I love Gain Fireworks, i through the into the cupboard with our blankets and towels to keep them sweeping fresh year round! You might say I have a little addiction to the smell on the Original Gain Scent in general

I love this product. It makes all my clothes smell great. And the scent lasts for weeks. I was only going to try it on my towels at first but I just loved it so much that I am using it in all of my loads. I have taken clothes out that were washed a few weeks ago and they still smell great. And the scent last even after the clothes have been worn. It is great stuff.

I have been a gain user for years.
I picked these up about a year ago and have been hooked since. I use them on my camping and other seasonal clothing items before packing them away and even after winter my clothes still smell great.

J'aime tellement ce produit de Gain! Il sent tellement bon et l'odeur reste tellement longtemps! Gain font d'excellents produits et ils font parti de mon top3 de produits pour le lavage préférés! Celui-ci laisse une douce odeur de fraîcheur et d'été! J'en mets dans mes vêtements, dans les serviettes et quand je lave le lit!

I love love love these! My laundry smells amazing and the great smell lasts! I don't usually put a full cap in the load (unless i'm doing towels) as I find the scent transfers to my hands fairly easily if too much of the product is used. I love these little things and will never turn back!

I also use them in my linen closet to keep my towels and sheets smelling fresh, and in my clothing drawers. So versatile and smell so fantastic. A great addition to the laundry routine.

Gain Fireworks Scent Booster are amazing! I'm really big on scent so I love the smell of fresh laundry except most of the time the scent doesn't last. Until I got a free bottle of Gain Fireworks to try out and OMG do they every smell nice. They kept my clothes smelling fresh for weeks. Every-time I open my drawer to look for fresh clothes the whole drawer smells nice. The best part it actually makes my husband's hockey stuff which he wears for hockey smell nice. (that is huge) Anyone who plays hockey or has a husband/kids that plays ice hockey will understand what I mean. LOL

I love the smell of Gain so of course anything that will make it last longer is great. I use scent boosters mostly on bedding and other loads where the fabric is used more than once between washes.
