Before purchasing my first genesis style atty, the Reo Grand with the Cisco LR 1.5 was my favorite all day vaping machine. Once the squonk is learned, it's a real pleasure to use, and the flavor sings because it's as close to Direct Dripping as I'd ever gotten without the mess.
But then I discovered the direct dripping flavor and no squonking needed of the genuine DID genesis and the rest is history. I still carry the Reo about, in my purse pocket, for "just in case", but I haven't touched it in months.
My favorite to date:
Roller telescopic mod by Atmizoo
Mini DID and DID20 by MMVapors (now have a Gemini too & I'm sure it will be in this top favorite list as well after I try it later today).
B.A.M. by theGreen with a Kick. It's huge, but it's VERY comfortable to handle.
Silver Bullet is still one of my faves for outdoor projects. It fits nicely in my back jean pocket.
LavaTube is still working for me, and soon I hope to purchase a Metallic Pink V2 one. It hits great, tests my battery life, and is lightweight and easy to use with it's user friendly menu.
eGo-Twist... I know I know, it's not a "mod", but it's such a handy gadget and deserves an honorary place. With a Mini DID on it, it's sleek, lightweight, and produces wonderfully.
Least Favorite:
Zenesis Standard. I really appreciate how Zen brought the genesis to the newbies like self. He went above and beyond to help us newbies get started with the genesis. Unfortunately, this is also where I learned how much I hate, no, despise, hybrids. If the atty is a bad atty day, (which all genesis builders go through even when they're pro's at building them), you can't take the atty off and use the mod with a different working atty. If the mod itself needs fixing, like say the BUTTON, then you have nothing but a stupid expensive paperweight sitting around until the button is fixed. Sometimes, that can take months or maybe even years. So, even though I appreciate the craftsmanship and beauty of a hybrid, I can't see myself ever buying another one ever. But, with that said, I am looking forward to eventually marrying one of my DID's to the new Poldiac that Jim the DID man has tailored made for us vapers. It can be married/locked to the DID, or it can stay free and flirty. Gotta love that!! (plus it's a real BEAUTY!!) After I get a few more mods and DID's under my roof, I just might lock a set one day. Maybe. It's nice to have the option.
