I just started using these a month ago, and the results I've seen in my skin are amazing! It's so much smoothr and brighter than it was before. These do so much for being so gentle! I LOVE the way they feel on my skin. If you're wondering if it's scratchy like a loofah, it's not scratchy at all! It's extremely soft. I've heard some people describe it as a "rubbery texture", which isn't an exact representation of how it feels, but it's as close a description as I can think of. Using one on your face is so relaxing. I also haven't been running out of face wash as quickly - you only need a little drop, since konjac sponges create such a rich lather. I've only used my Clarisonic once or twice in the last month - so far, I prefer these, since they seem to be a lot gentler on my skin and don't cause any irritation whatsoever. I just got my mom hooked, too! And honestly, $7 for two sponges? I haven't found a sponge anywhere near that reasonable anywhere else, especially for such great quality! The string you hang it by hasn't pulled out of the sponge - it's very sturdy. If you haven't already, please give these a try - the konjac sponge has been a total game changer for me!!!
