Good product--should have bought sooner! [SEP] This works exactly as stated. Mine came perfectly boxed with all parts and an instruction booklet. So far the batteries keep their charge for a long time--I have used it briefly on occasion and now, today, continuously for about a half an hour and they still haven't hesitated. The cord included is the spiral type (&#34;telephone&#34;-style) so it can be stretched as needed, should I want to use the unit for a longer time. The filing bits appear sturdy and made very short work of my fingernails. However, I purchased this for my unusually hard toenails and it worked like a dream to file those down in short order! I love this product and it seems to be worth the $26--much better than the other cheaper device that I have been struggling with. My only problem: Why did I wait so long to order it?
