I am very satisfied with the quality of the purchase. It will be more than adequate for any jobs I have around thee house. The lighted female end of the wire tells me that there is power there and if there is a problem it's in the tool. Likewise if there is no light there then i look to a tripped breaker and this saves time and trouble. If there is one thing I would think would make it even better is more flexability in the wire. I realize that there is wire with that flexability on the market but the projects I have doesn't warrent that extra cost. All in all I am very satisfied. thank you very much.
