When I say this unit was durable, Im talking went to Mexico for a Bach trip and went boating, beaching, cliff jumping in the cenotes, zip lining upside down and riding on ATVs; when I got back a week and a half later the waves were still perfectly in tact! (S/o to my stylist for a next level install) but the hair was soooo soft with hardly any shedding at all and I was brushing, detangling and pounding tons of product into it. Super quick shipping too. All in all 10/10 experience. Also! Looked just as good on the second install!
