I can't help you with a GT3, and good luck with that, nobody let's theirs go, but I was litterally about to post this for sale. It's my first dicodes I got a couple years ago and though she is a little beat up (light scratches, could likely be buffed out and you can still buy the ext tubes), she is a tank. You could toss it off your house on your driveway and it would be fine, although I would not recommend it. All of Dicodes tubes are built like brick shit houses, to use the technical term, but I feel like this one is the toughest of all - certainly tougher than my Dani25 I have to smack sometimes to get it to turn on. She is the 2380T and you can even stack her for double wattage:
- 40 watt (1 x 18350/18500/18650)
- 80 watt (2 x 18350/18500/18650)
PLUS - should you find your GT3 ever, it will look lovely on her as they are both 23mm
