Review on Complete Your Travel Essentials with True Essence Cobalt Bottles Roller Accessories! by Darin Merriwether

I was waiting for a review when I actually had the chance to use these mini roller bottles. Last week (February 2020) my husband and I caught the flu so to keep us both comfortable I split our 10ml breath mix video into two smaller ones because in this case sharing doesn't matter. I soon found that the rolling balls were not rolling. My husband was finally able to do his job minimally. I tried all the roller attachments and none worked. Since we only got sick after the return period had expired, we are unfortunately unable to return them. I am extremely disappointed.
