On the autism spectrum [SEP] My 3 year old boy is on the autism spectrum and sense he was one year old I only give him 3 to 5 hair cuts a year. He is afraid of the sound, hair falling and feeling. This product is great idea minimum sound and small to hold with one hand. Presentation of packaging is great. I give it 4 stars because it states water proof. After reading the instructions It says washable, not submersible. I wanted to go in the shower and cut his hair. I still give it a try, but as soon as he saw the clippers he ran out of the shower naked, screaming and scared. The product is good, but it did not work for me.
