"A Skip It verdict with a BrickScore of 29.9: the Smart Brick sound effects provide real fun for young children, but only 26% of LEGO.com purchasers would recommend this set, and a price-per-piece of $0.148 for an incomplete-looking 473-piece model leaves experienced builders and value-conscious buyers firmly unconvinced."
Darth Vader's TIE Fighter (75421) is a 2026 Smart Play set that earns a BrickScore of 29.9 and a Skip It verdict, reflecting what experts judge as a fundamental mismatch between the set's appeal and its $69.99 asking price for 473 pieces. The set's owner signal is markedly split: Amazon buyers average 4.6 stars, but LEGO.com purchasers are more measured at 4.0 stars, and LEGO's own data shows only 26% of owners would recommend it, alongside value_for_money averaging just 2.66 out of 5. The Smart Brick interactive feature generates genuine enthusiasm among families with young children, but the aspect consensus across design, display, and minifigures all sits in the 25 to 50 range, indicating the core set underperforms independent of the electronic element.
Where they split: The split between Amazon's 4.6-star average and LEGO.com's 4.0-star average, combined with the 26% would-recommend rate, suggests the set over-indexes on impulse or gift purchases (captured in Amazon ratings) but underdelivers for buyers who engage more deeply with the set (reflected in LEGO.com signals). The BrickScore of 29.9 aligns with the LEGO.com owner signal rather than the Amazon surface average.

MandRproductions"Why does the entire rear half of the fuselage have to be completely open just to have access to the smart brick? I have not heard anyone give a good explanation for that yet."

Owners overwhelmingly praise the Darth Vader TIE Fighter for its engaging smart brick technology, sturdy build quality, and fun interactive play, though some find the price high and wish for richer sound design.
