Eber Anthony | October 2020
"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."

Joshua Goldman | April 2017
"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
