"With a BrickScore of 90.5, the Diagon Alley GWP is Highly Recommended for Harry Potter collectors and display builders: the architectural detail, exclusive Ollivander minifigure, and printed cobblestone tiles make it one of the most rewarding promotional sets LEGO has released, though the microscale format is a genuine filter for buyer satisfaction."
Expert reviewers from Jay's Brick Blog and Brickset both gave the 40289 Diagon Alley GWP strong marks, praising its colorful architectural accuracy, clever microscale building techniques, and the exclusive Garrick Ollivander minifigure as a standout bonus for Harry Potter collectors. The build experience drew more mixed feedback, with some finding the alignment of 1x1 plates tedious at microscale. A notable split exists with owner ratings: the 100% LEGO.com would-recommend rate from buyers contrasts with a 3.92 average across 162 Amazon and LEGO.com reviews, reflecting a segment of buyers disappointed by the microscale format or the cost of the qualifying purchase.
Where they split: A clear critic-owner split is present. Expert reviewers scored it 80-100, enthusiastically recommending it as one of the best GWPs LEGO has produced. Amazon owner ratings averaged 3.9 out of 5, reflecting a wider buyer base that includes people disappointed by the microscale format or the qualifying-spend barrier. The LEGO.com 100% recommendation rate from the small direct sample aligns with the expert view.

Owners appreciate this mini set as a display piece that captures Diagon Alley charm, though they find the £80 price point steep for a build with limited play value.
