    Really nice kit and good value. Bought for my ten year old who enjoyed the build even with an overly enthusiastic dad looking over his shoulder.
    I stopped building Lego models 35 years ago but this reminded me of how much fun we can all have without staring at a screen all the time. Maybe something I'll add to my next birthday list...
