If you’re on a budget and mainly use your laptop for everyday tasks like browsing the internet, working on documents, or streaming videos, the Dell Inspiron 15 3511 offers a good balance of affordability and function. It's also lighter, which makes it more portable. On the other hand, if you require a laptop for more demanding applications like 3D modeling, machine learning, or gaming, the Eluktronics RP-15, while more expensive, provides significantly higher performance, but with reduced portability and likely a shorter battery life due to its more powerful components. Consider how you plan to use the laptop and whether performance or cost is your main concern. Give Feedback

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."

"To conclude, I’m genuinely impressed with Eluktronics and what they have been able to deliver with the RP-15. You see this is all about maximizing performance, cooling, and giving users the most flexible I/O, and then wrapping it into a chassis that doesn’t feel super cheap. Let’s also not forget the price point, I think they have really nailed it in that department."
