Have two EVIC Vtwo (mine, and wife's), and they must be 6+ years old now. (Heavily used every day)
The amazing thing is what mine already went through...from busted USB ports (this is what usually goes first), to multiple repair/re-solder etc. AND IT STILL WORKS.
One issue that happens after some years is also that the buttons get unreliable, either multi-clicking or corrosion etc. (Same as with mice, or game controllers). Problem: These are tiny SMD buttons and not easily replaceable by a long shot. But I have a method soaking the part of the PCB with the button in vinegar, and then in ISO alc..and this has always revived the buttons.
And of course the magnets all some months coming lose and you need to glue them back.
That being said, I think these old EVICs are the best mods, ever. (I want to slap myself I didn't buy one on ali two weeks ago, some vendor had a sale of the EVIC Dual for €13 or so...)
** also had one or two isticks long ago, but these had loooong failed. Total garbage and no comparison to the EVIC.
** just out of curiosity (since I want a new mod that I can flash with ArcticFox), I just ordered a Vaporflash Stout from ALI for like €12
