Update June 2021: I found myself loving the ASNME brush so much that I decided to buy a second one for the shower. I was disappointed to find that the original product was no longer available and spent months regretting that I hadn't purchased a second one. Then I found an updated version! I can verify that it is indeed the ASNME brand, with some improvements. One of my complaints about the first version was that the blue light wasn't on it's own click (you had to first use the red light all the way through, and then the blue light came on). They have now fixed this so that you can cycle through directly to the blue light. Excellent! I would say that the brush speed has also changed from the original and it is a little stronger now. The brush itself is still soft and nice for sensitive skin. In my original review, I said I also liked the EZBASICS brush. But over time, I have found that I really don't care for that one anymore. It is too firm. I exclusively use the ASNME brush now, and I gave my husband my EZBASICS brush so that he has one in the shower as well. He does like that one a lot, but I prefer the softer ASNME brush. Please reference my original review below, for a detailed comparison between 4 different brands of brushes.In case anyone else is interested in getting the updated one, here is the link: https://www.amazon.com/dp/B08TLRVBBMOriginal Review:I put 4 silicone cleansing brushes head-to-head. I'm giving a summary of my impressions and decision first, if you don't want to get into the fine details. Keep reading beyond that, if you want more detail.Final thoughts: In the end, I decided to send back the PMD. While I loved the feel of the rose quartz and the heat, I just didn't like the silicone brush at all. And the hefty price tag was enough to convince me to send it back. I really liked the feel of the Chitronic device, and if the heat had functioned better, I might have kept that one, at least for a brush to keep in the shower. But since the heat was negligible, and the brush was more expensive than the EZBASICS brush, I ended up sending the Chitronic back.WINNERS: In the end, I kept 2 brushes. I like the ASNME device since it has the heated plate for applying serums and the silicone bristles are super-soft (I have rosacea and sensitive skin). The portability and price are also excellent. I'll have to search for a travel pouch of some kind. And as for a drying cup, I found out that a nice-quality sink strainer is the perfect size for placing the device to dry, bristles down. I have the ASNME brush by my sink, but I decided to also keep the EZBASICS brush for my shower. I really like the way the brush feels in my hand, the way it can get into tight spots, the nice vibration, and the excellent price. Unfortunately, my husband liked it too and hijacked it! I had to buy a second one for myself, haha.Detailed review: please refer to my photo with a chart of the functions and my number rating for each device. In my pics, the pink brush is the PMD, the teal brush is the ASNME, the lighter teal brush is the Chitronic, and the blue is the EZBASICS. I ordered the EZBASICS after I had tried and returned two of the brushes, and so there is not one pic that has all of the brushes together.1. Feel of the brush head: My preference here is the Chitronic device. The bristles are dense and soft and there are bristles all the way out to the edge, allowing it to get into tight spaces easily, like around the nose. The ASNME bristles are the softest and are backed with a flexible silicone pillow of sorts, making it feel super soft and delicate, and might be the best choice for sensitive skin. The bristles are not as dense, however, as the other devices. The EZBASICS bristles are fairly short and not as soft, but I do like the shape of the brush and how easy it is to get in an around the nose area. It is the best for maneuvering into tight spaces. My least favorite is the PMD as the bristles feel harder to me, they don't come out to the edge, the brush head is smaller, and I really dislike the small section at the top with thicker, harder bristles. Those end up being the bristles that go into tight spaces which is fine around the nose, but not fine around the eyes. Too harsh.2. Heat function: My favorite here is the PMD device. I really like the feel of the rose quartz, the heat is just right, and you can keep the heat on for as long as desired while applying serums and moisturizers. It feels divine! The ASNME has a similar function, but with a metal plate. It's still nice, but not as nice as the quartz, and the red light/heat setting only lasts for about 1.5 minutes, which isn't long enough. Therefore, I have to turn off the device and turn it back on, pressing several times to get back to the heat. After the red cycle ends, the thing will switch itself to the blue light automatically, with vibration. That's okay, but I prefer the red and I wish the two functions had their own button-press associated with it. You cannot enter the blue light function without first waiting for the red light to do its thing and you cannot just keep the red light and heat on for as long as you want. That's my biggest complaint about this device. Also, the product posting says that the blue light is accompanied by heat, but mine is not. The heat shuts down when the red light function ends. The Chitronic has a heat setting, but no flat plate for applying serums. Plus, the heat is barely discernible. It also has a supposedly heated purple light for disinfecting and drying the bristles, but the bristles are always wet afterward, so I'm not sure it's very effective. The EZBASICS does not have a heat function, although the back side has ridges for massage, so maybe that side could be used for applying serums, without heat?3. Sonic vibration: The PMD has the most intense vibration (adjustable) and I feel that it would be more effective at cleaning out the pores because of it. There are several settings to choose from. The intense vibration might not be the best for sensitive skin, however. The EZBASICS, on high, is almost as intense as the PMD, and I prefer the feel of it (not so bone-rattling), and you can adjust the vibration to be more or less intense as desired. The Chitronic is next in line and again there are several settings and you can also increase/decrease the intensity. The ASNME has the least vibration and I feel like the vibration is stronger on the metal plate side than it is on the brush side. That's disappointing, but maybe it would be again better for sensitive skin. It does have two intensities to choose from.4. Portability: The ASNME device is the smallest and would travel well and would even fit into a small purse. Since there is no handle, it would be less likely to break in my opinion. The EZBASICS device is larger, but very thin, so it would still travel very well. The Chitronic is also very small, but a handle does protrude. The PMD is the biggest device and would take up the most space, especially when put into its travel case. It is the only brush that included a travel case, however.5. Light therapy: I gave the win here to the ASNME device, as it has red, blue, and green light therapy. The Chitronic has red and blue lights and a purple light for sanitizing. The ASNME red light is nice in that it is accompanied by a soothing warmth that I really like. The PMD and EZBASICS devices do not have light therapy. All of this being said, however, I feel like the light therapy is a little gimmicky. I'm not sure it would do much over such a short session.6. Grip: The PMD has a superior grip to the other devices. I rather like the feel of the EZBASICS brush and it doesn't slip out of my hand. The Chitronic isn't bad since it has a handle. The ASNME is simply gripped along the outside edge; and since it is small, it feels a little bit less secure in the hand and can get a little slippery, especially when applying serums and moisturizers.7. Charging ease: All 4 devices supposedly keep a charge for a very long time. I find the ASNME the easiest to charge as the connection is magnetic. The EZBASICS brush is close behind as it is also wireless and includes the wireless stand for charging. The fact that a separate piece is needed for charging is why I rated it second. The Chitronic and PMD devices both need a plug to be inserted which seems like it would make them a little less waterproof, even though the hole is covered by silicone. The PMD was the hardest to get plugged in. I had some resistance.8. Timer: the EZBASICS brush and the Chitronic brushes have a timer function and will shut off automatically when cleansing. The EZBASICS shuts off after 5 minutes, however, which is awfully long and seems more like a timer to keep from running the battery down too quickly. The Chitronic goes for 2 minutes which is a better amount of time for cleansing so the Chitronic wins. Neither the PMD or the ASNME devices have a cleansing timer. The ASNME device does have a timer for the light functions, but I'm actually annoyed by that timer, thereby earning the lowest ranking.9. Accessories: All four devices come with a charger cable. None of them include the actual wall plug so you have to supply that. The PMD comes with a hard travel case. It needs no drying rack because it can stand up (although, it is kind of tippy which would worry me as falling might cause the quartz to break). The Chitronic comes with a plastic cup for drying the device but no travel case. The ASNME and the EZBASICS have no accessories (other than the charger). I wish they came with a travel pouch/case and a drying stand.10. Price: The PMD is significantly more expensive than the other two devices. I paid $120 for it. Chitronic and ASNME were both under $30 and were similarly priced. The cheapest of all 4 was the EZBASICS device and I got it for around $18.
