I'm very happy with this charger. It has given my HP Laptop a full charge and a new lease of life so I no longer get a message saying the charger cannot be identified and may not charge which happened with the aging HP charger I had which had a frayed cord. The charger is hexagonal as is the laptop charger so fits snugly. I received the item within 3 days and at a half of price that what the charger would cost from HP. I cant comment on the charger longevity yet but it looks well made and a good purchase.
