this review title is: potential safety concern and the content is: maybe it was just this particular unit but the one time i used it was enough for me between needing to use it while it was powered off and plugged in the device got increasingly hotter to the touch i was afraid it may actually cause a fire it did the job but i bought it days ago and sadly it was returned today for safety concerns.there are other information for this review, one is this reviewer did purchase it and the other is 1 people think this review is helpful.
