Would I recommend the XQ2 over the Ditanium? I feel comfortable recommending either or both, as they are both great vapes.
Every vape recommended on this thread so far, so far as I can tell is a great vape. There isn't one I wouldn't be pleased to own, and I imagine you will be pleased with whichever selection you make. You might also regret not getting another vape that was suggested, or you might find your vape needs expand, as so many of us have, and start to Build the Collection. Not because you are dissatisfied with your selection, but because you are so pleased with your choice, that you want even more vape joy and to find out how other vapes perform for you.
Even if you only want one desktop, I can say the Arizer XQ2 or the Ditanium will serve you well and are good vapes. If I somehow lost them both, I'd replace them both. They are both used and loved.
I wanted to wish you luck in finding the current right vape. It's fun, and a good way to meet the many helpful and kind people on FC.
Also, at 421Store (online) the Arizer XQ2 is 40% off until January 8th, 2024. The sale price is $149.99, and the code is 'Arizer' , shipping free.
Also, Planet of the Vapes, POTV, has a clearance section, and open box or returned vapes at nice discounts. Sometimes Ditanium show up there. I just checked, and they have an Arizer EQ for $100 right now. That's the model before the XQ2, and we'll worth $100 to my mind. The Arizer EQ was my first vape, and I have and use it still. I think it's 6 years next month. Never a problem with it, and it blows bags, which some like.
And, as far as needing to preheat your desktop, I just turn mine on when I'm home, and they are ready as I need them.
May you find your next favorite vape. Enjoy.
