I do have 2 SVDs that still work
LOL, SVD 1.0's, got 2 myself. Both still function for the most part, in the emergency don't have another vape device cache atm. Still use my 3rd, a 2.0 with the DNA20 chip in it, still works like a charm. Still the SVD 1.0 was my first official 18650 mod I ever bought and got me through a full year before the first had issues with the buttons for power adjustment, 2nd 1.0 likes to shut down for no apparent reason during use, something with the fire button on it.
Other dinosaur gear in the collection:
Reo Grande with an A7 Mini BF
Provari Mini 2.5
Several Mechs
IPV2 and IPV3
iTaste VV V3
Sigelei 30W Mini and a Sig150 Original
Most recent mod I have was an X-Mas Present to myself last year, an HCigar vt75 (gotta love the battery life on a 26650 with it with only a Kayfun at 8watts going).
