Affordable brands offer Lego-compatible bricks

Several affordable building block brands offer compatibility with original Lego bricks. These alternatives provide a budget-friendly way to expand collections. Brands like WYSWYG, Insoon, Katara, Burgkidz, and Strictly Briks are highlighted for their quality and compatibility. They offer a variety of sets and pieces, often at a lower price point than Lego. Lego's patent expiration in 2010 allowed for compatible third-party products. While generally good, buyers should check for minor differences in instructions or figure appearance.
