Haven't had it long, or used it much but has performed extremely well so far. Easy open cap, once i figured out that i had to use my fingernail or a small screwdriver to get down into the safety latch to open it. Opened easily. I had a pair of small wire cutters that i used for craftwork. they had gotten a bit rusted somehow from lack of use and incorrect storeage, apparently. This oil loosened the joints and removed the rust easily.
