This LED lights did not stick to my walls. I set them up in my room (efficiently, I made sure they shouldnt fall off) and left for a couple hours. When I came back they had completely fallen off. I messaged them to see if I could get my money back or if another one could be sent to me because I thought maybe the one I received was defective and they never even responded and its been 2 weeks.

Ex Output:
negative

I purchased this item to use for my sons prom send off, the only balloons that were able to be used were the latex ones, no foil balloons could be used, also the discription shows a 2018, I was sent a 2019, which means the day of prom last minute I had to go and purchase the correct numbers which cost me an extra 40 dollars... I'm so disappointed..

Ex Output:
negative

I am absolutely in love with this product! I have very dark, thick hair and my natural skin tone is pretty fair so I am a good candidate for this device. You have to be consistent with this device for it to work because your hair grows in cycles. I was very skeptical of using Flawless but decided to give it a try and could not believe how "flawless" my skin looked afterwards!! Even the next day my skin was feeling smooth. It doesn't hurt at all and literally only takes a minute. I have even gotten compliments on my skin! I can not say enough good things about this product. It has given me so much confidence

Ex Output:
positive
