My first, a Phidias, acquired almost exactly 3 years ago, is still going strong, as are all of my mods from the first year---Darwin, GLV, Provari (purchased used, version 1), Vmod XL and a couple other classics from the classies (like Roughstack & The Mini Grip Feeder). The mini's/cig alikes are long gone as are my first ego's.
The only mods that have died have been some of the next year's purchases, non USA made mods and quite frankly, cheaper models.
