"i have not played seriously with lego for 40 years ,apart from basic things with my grandchildren , i am disabled and in bad health and in need for something to occupy my mind and time, on my birthday 2 weeks ago i did not know what to think when my family bought me the technics rough terrain crane when i looked at the size of the box the amount of packets and how thick the instruction manuals are i was worried to say the least . i sat down and began packet 1 and was really happy how clear everything is the manual very clear in where things go and pegs coloured i made progress in no time apart from the odd peg the wrong way round which is usually easy to see when you try to put the next piece on it and it wont fir the peg shape i am doing 1 to 2 hrs a time and making great progress i love it im about half way in all that i made two mistakes but when spotted were easy to rectify in a short time , technic is not like normal lego blocks but is so fantastic ,how this is designed so great . cannot wait to finish then pick one out of a mounting list i have to do , fatastic lego include adult things too , the prices range from around £10 to £550 somthing for everyone ,i would recommend lego technics without a second thought ."
