I don't think I have ever written a bad review about any product but this was a huge waste of my money so I am reluctant to pay to send it back to the company. This product is defective. I read the instructions, charged it fully before my very first use and I feel I used more product, not less, to get this to glide along my face smoothly and I felt I had to run it for a very long time and still my serum did not penetrate into my skin. I finally just gave up and applied the rest of my moisturizer manually. That was the first and only time it ran for any length of time before losing its charge after a few seconds of use. I really wanted to like this product and was so excited to try it. At this point I wouldn't recommend it, save your money. UPDATE, I was contacted directly by the General Manager, Michael, of Michael Todd. He did some troubleshooting with me regarding this product. The wand must be placed on the cradle facing away from you. In other words, the indicator light should face away from you and the words on the device should face you. Which feels counterintuitive being that most tools that recharge have an indicator light that faces you or the cradle indicates the tool has made proper contact and is charging if the tool has to face away from you. After that, the device did charge properly. I was able to use this to apply my serum and moisturizers without the device dieing. It did warm up and after some trial and error I figured out how much product to use. I do feel I used less than I would have applying the serums and moisturizers with my hands alone. What remains to be seen is whether or not I feel it helps the serums and moisturizers penetrate more deeply or seeing greater results do to that. I will update again after using this device for a while. If I feel it does yield better results due to deeper penetration of the products I will give this to give stars. In do feel this product works well, it gives me such a glow and feels great after a stressful day. I don't have fine lines or wrinkles so I can't comment on seeing any reduction in the appearance of fine lines or wrinkles but I also don't want to form any, at least no time soon. For the price I would recommend it, especially if you are regimented. I use it every night on weekdays because I don't have time in the mornings and I use it twice on weekends since I don't have to be anywhere by a certain time. If you can use it morning and night daily you will definitely get your money's worth.UPDATE: As mentioned in other reviews, mine quit working after 2 months. I really liked using this but so disappointed that it quit working.I initially purchased the Soniceraser from a home shopping channel. They only give you 30 days to return an item so I decided to return mine because I didn’t think I was seeing results. I was wrong. I didn’t realize how smooth my skin was until after I was no longer using the Soniceraser. My skin started breaking out again and felt rough. Needless to say, I bought it again, here on Amazon. This thing really does work, I just didn’t give it the benefit of a doubt. To be honest, I only used it once a day opposed to twice a day as recommended but I’m telling you, this works. I mix together my moisturizer, vitamin C serum and hyaluronic acid. I spread it on my face and neck, then use the Soniceraser to work it in. I found that I didn’t use up too much product this way. I will be using it twice a day, going forward.Use this as recommended, give it time to see results and you will not be disappointed.I've been using this for a month and a half with Baeboy under eye gel, as well as the Nuface face toning device. And as well as an anti-aging moisturizer. Yeah, I went all in because I had terribly puffiness under the eyes and dark circles. Within a week, I stopped wearing foundation all together. It's a little weird skipping the foundation and under eye concealer but after I put on my eyeliner and eye shadow and lipstick and mascara, I can honestly look in the mirror and feel satisfyingly made-up. I tried not using make up in the past and always felt unkept. If I use this (and the rest) every day, no circles and no puffiness. Foundation seems fake and just sits on top of my skin. So, I think worth the buy.I liked this gadget immediately and talked a friend into getting one. Until you figure out how to operate it that it has to be touching your skin before iti works takes a little getting used to. I got the pink one, it doesn't pull, and I enjoy the warmth it provides. I will let you know if I think it is working.I've had a Clarisonic Opal for a few years, but this is much, much better. The heat and vibrations help infuse the serums, cream into the skin and it actually helps the puffiness under my eyes. My skin is looking much better, too.Really love this little gadgetI really love the product, but in June, 2019, it started to not hold its charge and there were times when it just wouldn't turn off. I had to slap it to get it to stop. Finally, it would't hold a charge for more than two days so I contacted Michael Todd Beauty and they told me , sorry, but it's out of warranty. I replied that other companies stand behind their product and would at least offer a "loyal customer" discount, which they finally did, all of $11.90! Since I really love it and don't know of another similar product, I got it on Amazon, where I had points.I am 71 and recently began modeling again. I did a photo shoot and the make up artist used this device and I was amazed at how I worked 8 hours and my face stayed fresh! I immediately bought this and am very pleased. My lines didn’t magically disappear, which would have made me ecstatic, but I do look better. Very pleased.
