Boulder Blaster Reviews
Eurobricks
“A decent set. The main function is not as good as, say, the Thunder Driller, but the other, smaller features make this set a must-have for any self-respecting Power Miners fan or someone looking for a good buy.”
BrickEconomy Expert Review
“The construction of this set is straightforward and robust, not taking much time and involving minimal repetition, mainly for the treads and plows. The highlight for me is the engine block design, which impresses with its functional appearance despite lacking moving parts. However, the hood, adorned with a large '7' sticker, is a bit flimsy and tends to detach more easily than expected, but it's not a significant issue.”
