There are many good methods. They aren’t hard to learn as long as you can memorize a few 7-10 move algorithms.

For people recommending using screwdrivers and sticker peeling, they’re actually much easier than that to disassemble and reassemble. Turn one face 45 deg. Pop an edge up. The whole thing will fall apart. Tougher to assemble but not too bad. Only problem is you have a 2/3 change to accidentally assemble an unsolvable corner rotation and a 50% chance to assemble an unsolvable edge flip. Both are easily fixed if you can spot it by flipping any edge and rotating any corners once or twice as needed, but then if you’re able to spot it, you already know that.
