As expected, it feels bulky in my hands, with some buttons too spaced out to be convenient to press. Regarding shape and weight, the Legion Go has a massive 8.8-inch screen and weighs relatively a lot for a gaming handheld at 1.88 pounds. The Lenovo Legion Go is bulky from the front, but its grips are ergonomic and thinner than you'd think. They can then be reattached by being pressed back into position and up until there's a click. A button on the bottom of either controller must be pressed, and then the controller must be wiggled slightly while being pulled down from the display before they will come off. Instead of sliding on and off the system from the top like the Nintendo Switch controllers do, the Legion Go controllers do more of a popping on-and-off motion. It took a lot of practice before I learned how to quickly detach the controllers, as the action is not nearly as easy as it is with the Nintendo Switch. Otherwise, they stay very securely attached. They can only be removed if I intend for it to happen. I thought there would be some wiggling or creaking from the detachable controllers, but this is not the case.
The overall look of the Legion Go casing is boxy and somewhat unattractive however, it has a very sturdy build, and the large screen outshines the controllers right in front of you.
