on the autism spectrum [SEP] my year old boy is on the autism spectrum and sense he was one year old i only give him to 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 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
