PCMag

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

Alex Iliev | August 2022
"Chances are high that the HP 15 is one of the first laptops to pop up when you search for an inexpensive notebook. Indeed, its price tag is very tempting for many, and of course, this is the reason for its popularity. However, the HP 15" suffers from poor performance due to low power consumption. On the bright side, one of the good things about it is the port selection. On the inside, this includes two SODIMM slots for memory, an M.2 PCIe x4 slot for storage, and a SATA drive bay. However, the TN panel, and mediocre input devices are not ideal."
