I bought this AC adapter for my Dell Inspiron 15 laptop to replace the original AC adapter which I accidentally destroyed with a vacuum cleaner. I've been using this power supply for 5 days of heavy use and haven't had any problems. So far this power supply works great with the laptop and I am completely satisfied with the purchase. The adapter block feels warm but does not heat up. The specifications of 45W, 19.5V and 2.31A are exactly the same as the original power supply. For the price, this is a great buy for me. The only difference between the OEM power supply and this one is that the OEM power supply was a 3 prong with a ground pin while this plug is only 2 prong. I didn't notice this when I bought the power supply, but it's clearly visible in the picture, so I've got it on. I hope that won't be a problem. I will update if there are any durability issues or other issues. Update 3/7/20: Still working great, no issues.
