fell apart after two uses [SEP] i only got to use the product twice before it fell apart when i went to use it the third timewhen it first arrived i fill the reservoir with some of the oil i have the roller applied it evenly on my skin it was smooth and there was no discomfort however it did seem that some oil was leaking out of the reservoir as i used it i also found oil pooling on the bottom of the productwhen i went to use it the third time the roller itself popped off as i tried removing the cover from it no matter what i did even after emptying the reservoir and drying it the roller would not stay on maybe it is a defect with mine but i had to junk it
