[EX Q]: The toaster oven worked fine, but the different 'functions' were pretty much the same thing. The heating element stopped working after a year. Keep shopping.
[EX A]: negative

[EX Q]: Reformulated in Jan 2018 - horrible. Super runny, no lather. Seems like a ploy to get you to use 2-3x as much product each wash as it just flops everywhere when you try and squeeze a little amount out. My breakouts are back to what there were before. The old formula had pretty much cleared me up. One week with this new one and I’m back to being self-conscious again. I’m going to scour local drugstores for the old version and if I can’t find it, switch brands.
[EX A]: negative

[EX Q]: For me it is used in my hair straighter and hair dryer brought from China. It is useful now and i’ll use it continuously then i could come back to write another review.
[EX A]:
positive
