[EX Q]: Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.
[EX A]: negative

[EX Q]: Just received this rosehip oil and unfortunately it smells like rancid fish oil supplements. The smell is noxious when opening the bottle, but I tried some on my hand to see if the odor would possibly dissipate. Very wishful thinking as I smell like dead fish and it has been over 30 mins. Very disappointed.
[EX A]: negative

[EX Q]: Even though it isn't big, it is So Easy to Operate. Having Herniated Discs in my Neck & Bulging Discs in my Lower Back, I can operate this Machine without putting to much pressure on my Back.
[EX A]:
positive
