Liangshifu sound-off bladeless Tower Fan A6 (silvery)

looks like Dyson, sounds like Singer...high pitched whine at low speed...have to increase to medium to get away from whine...but is still LOUD. Have to turn TV up 5 notches to hear over it.. Arrived quickly, return without issue..Not the $400.00 of Dyson, but could just have a regular tower fan for the amount of noise...for 60.00 They need to make improvements.On the good side the ability to adjust the angle is nice and the air movement and rotation are fine.

Louder than I thought it would be but safer than any blade fan if you have young children

the noise is very laud.
