I've been building cigar box ukuleles for several years now. I've built Sopranos, Concerts, Tenors, Baritones, UBass and 8-String Tenors. In just about every instance, the quality of the parts was excellent, enabling me to build great sounding ukuleles that hit the proper notes up through the 12th fret and beyond. In the rare instance where one part of a kit may have been damaged in transit, I reached out to Mike via email and a replacement part was promptly shipped. I'll continue to source these kits from MGBGuitars as long as I continue to build them.
