The disappointment came when I opened up the kit and found out I had to do surface mount soldering. I've never done it before.....I waited too much time to open the kit and I can't open a dispute. On the positive side, when I contacted the store to get the files and instructions on how to assemble the kit they replied promptly and provided all the info in a zip file. Wish me luck...I will learn how to solder surface mount components and then put this thing together...I hope I won't break it!
