I’ve been using Delia for a while now, and I’d say they’re a solid alternative. Classic Red is bold, Gold is smoother, and Dark Green is quite strong with a deep tobacco taste. If you want a reliable place to buy them, I recommend this site:
stik delia. They’ve got every Delia flavor in stock most of the time and the checkout process is smooth. I’ve ordered both packs and cartons from there and never had an issue. Definitely a good option if you want to explore something other than the usual HEETS line.
