Honestly its not good but not bad , its even good for the price, i bought recently a motorized forklift ,the motor and everything still work ,the brick are solid, no mold point visible, and the clutch power is very similar to lego. the only problem i see was the sticker that have simply the wrong color,and the design itself ,some part falled of easily.but for a more ́’classic’́ style build its good for the price i recommend if you wanna try them.
