★★☆☆☆
Item worked as expected but caused severe reaction
The item was delivered and worked correctly. However, I got extremely dizzy after using as directed several times - the room was literally spinning. I also started seeing floaters (strings in your field of vision sometimes associated with cataracts/aging, which went away after I discontinued use of the device. Returned the item.
