Review: Great quality at the right price and good balance of pieces - Really happy with the quality. I was a staunch defender of the original brand, but Duplo just seem to produce sets with relatively low number of pieces and pieces that are very unique to the set. I just wanted loats of squared and rectangular pieces because the girl I bought this for is too little to build the set and loves doing her own creations, like I did when a kid. This is perfect! Has a right balance of piece's geometries, good price, quality (grear fit, not too tight, not too loose). This one is manufactured by Liangxing Toys Factory.
Review: Bright and strong - These blocks are bright and strong. They work well with our Duplo and have added hours of fun for my boys. If you want to build big things then I highly recommend these.
