A roller coaster of emotions.... So I finally used the RevAir on my hair this evening. I had previously used it on my son and had decided at that point that the RevAir had a permanent home. My son said mom “ this is so much better than the blow dryer”. I did not hear a single ouch from this tender headed kid, I think he forgot I was doing his hair because he was on his phone. And there was not a single piece of hair anywhere on the floor. But I digress....So I had great expectations going into this venture. But I should have known things would be interesting when I went to deep condition my hair and was out of 1 of my 2 staple deep conditioners , but I took it in stride trying a random deep conditioner I had brought last Black Friday. It was moisturizing but it did not melt the tangles like I’m used too. Deep conditioner was rinsed out and it was time to break out the RevAir. I went right to the high suction and tried the first section for about 30-45 seconds. It was dry but not as stretched as I thought...turns out the genius that is me, forgot to put the heat on. So I tried it again and YESSSS!!!! The heat didn’t even feel like heat, my hair was so stretched, no broken hairs, no smell of heated hair...a dream come true. I was on a roll going through sections of hair with speed I have never been able to achieve before. I had about 5 sections left (I did a total of @13 sections). I could not wait to go downstairs and sing the praises of RevAir to my family and then it happened....IT SHUT OFF ON ME, just turned right off. The light was still on in the room so there was no blown fuse, the dryer never felt hot so how did it over heat, but I said ok it was on for 40 mins straight so maybe it needs to “cool down”. I figured I would give it 10-15 minutes to cool down, but it would not turn back on. I tried everything I could think of, checking the circuit breaker in the basement, trying an outlet in another room, taking apart the filter, I read through every page of the manual for the second time, even enlisted the help of Others, but nothing, it would not turn on. Now here I am with 3/4 of my head done and I was UPSET to put it mildly, thinking well I guess someone has to get the defective product. An hour later, I begrudgingly dragged out my previously loved FHI dryer. The heat, the smell, the pieces of hair I wanted to cry. I finished my hair and went to call RevAir. I pretty much said to her what I have typed here and explained that I would be putting it back in the mail tomorrow and wanted a replacement. The customer service rep was so friendly and sympathetic, I must have sounded heartbroken. She said I think I know what maybe wrong. She had me check the back of the RevAir where there is a fuse switch and she asked me if it was black or if I could see white. I could see white and she told me to push it in and VIOLA it turned back on. I was so happy to hear that loud vacuum sound. Despite this evenings events...I LOVE THIS DRYER!! Question....are you ladies turning off the dryer in between sections?
