I have a hand held LED therapy unit but I wanted one that covered my whole face. My aesthetician uses one similar to this so I ordered one for home use. She recommended me using it for 30 minutes everyday if I wished. The unit was easy to put together by connecting the three sections. I like that it has several colors to choose from. It's easy to increase or decrease the timer. I don't use the fan as I feel like it doesn't actually blow out any air, maybe it's to cool the unit during use and not me. I have not noticed any plastic odor and it turns off without any clicking noise. It's really too early to tell if it's having a positive effect on my complexion. I also use the yellow light, to help with inflammation, on my knees.I am docking a star for the following reasons:I had to return the first unit because one of the connectors was buried inside.The second unit was missing a plastic screw cover.The cord is only about three feet long so you will probably need an extension cord.The instruction book is pretty much useless. The print is microscopic. I printed a screen shot of the color chart.I think it's a fair price for the unit and I will update my review in the coming months.
