Electronic Refillable Roller Bottle - 10ml Container for Hyaluronic Acid Serum Essence Essential Oil Massage Skin Care Reusable Bottle with Stainless Steel Roller Balls

No good

I'm a fanatic for anything that can help me slow down the aging process, so I've been using my roller everyday, several times a day, ever since I received it last week. So far I love it! It did take me a minute to get used to the vibration on my face, especially around my eyes, but other than that, it's GREAT, I absolutely love mine! I'm already addicted to it! I do think that if they provided some type of little funnel because as it turns out, it CAN BE a tiny bit messy adding your serum, especially if you don't have steady hands, but other than that, it's a great product, especially for the price.
