I've been using this semi-consistently for about 5 months now and I think it was a good purchase! I don't know much about IPL devices, but I liked the price on this one (as I write this it's listed for cheaper than what I paid) and the reviews seemed promising.I have light to medium skin with dark thick (not course) hair, I mostly use the device at a level 4 or 5. For the first month or two I used it weekly, but then I started grad school so now I use it maybe every 4-5 weeks. It is working well on my legs, the areas of regrowth are decreasing over time and returning more and more slowly. Progress on my underarms is slower--the whole area continues to grow, though the growth rate has significantly slowed down.Pros: auto mode makes treatments easier. Some devices looked like they needed new cartridges or something, I like that this one should last me for the time I need it and beyond. I like the progress that I'm seeing!Cons: I wish the chord were longer. The device gets hot pretty quickly when being used at higher levels. during treatment it's difficult to make sure that I cover the whole area, but this is a technique problem. Still, if there were a device that solved that problem somehow I would say to prioritize that in a purchase.All in all though, I think that this is a really solid and affordable option.
