EverSmile AlignerFresh Cleaning Spray for Invisalign and All Clear Aligners and Retainers – On-the-Go Cleaning & Teeth Whitening, Kills Bacteria, Fights Bad Breath – Mint Flavor, 10ml (1 Pack)

These came in a set of two clean sprays. They are each roughly the size of a lipstick and fit easily in your purse or pocket. The lid has a clear cover, so it won't go off until you use it. Great for when you can't brush your liners before you pop them back in after a lunch or snack. It tastes quite pleasant. At first, it has the taste of hydrogen peroxide, which is the cleaning part of the formula. Then you taste the sweetener, sucralose, which lasts longer. I feel cleaner after using this. Invisalign compatible. The box says 30 uses per bottle, but I haven't used it that many times to confirm or deny that claim.

This really does make the aligner smell fresh and clean. Need very little. Not sure it whitens but definitely freshens.

I agree with other reviewers the quantity is smaller than I anticipated. But since I only used it when I go out, the quantity is sufficient for me. I like the sweet minty taste and it does keep the tray clean. Before using it, the tray will be so ugly and it's nice to see the trays keeping clean over weeks of use. Pros: 1. Good taste 2. Travel size 3. Easy to use Cons: 1. Need at least 3 sprays for a tray and the quantity per tube is not high. No comment: Not sure if the whitening is working and not sure about the safety either (any regulation in the US about tray cleaner safety?)

I find this spray very convenient for cleaning trays while on the go. A couple pumps into the trays and they taste fresh.

I got these for my Invisaliners to carry in my purse. I really like how clean they make your breath feel. However, I can't keep them in my purse because some of the lids don't stay on. They also hold very little product and I find I'm going through the bottles fairly quickly, which is inconvenient. I wish the sprays were just a little bit bigger so they could still fit in your purse (or pocket) without replacing them so often. It also makes it feel like you're spending more money even though you get what seems to be a lot of product because of the bottle count you get. With a bit of tweaking, this could be a great product.

Perfect refresher to take with while traveling. I always feel like my retainer gets gross while traveling and they helps as a good in between when I can’t soak them. The mint taste is a nice touch. I keep it in my purse and it’s never leaked.

Perfect size to carry with you.

I need this spray and got the duo pack. I hike and need it for when I eat on the trails and to pop my Invisaligns back in, knowing that I've destroyed some of the bacteria! Great taste, doesn't bother me at all. A little pricey for the amount of spray you get, but one to keep at home and one for the backpack. I would buy again.
