I love my 4Nine in Copper, it feels like a toy compared to my Cartel and Fuhattan, even my Vanilla outweighs it. It's light, and tiny. It is a finicky mod with the hybrid top cap, definitely not for beginners. If you have a good understanding about all things mech, you can't go wrong with it. The only issue is some batteries and attys won't be compatible. LG's are fine, Sony's are too tall, and you have to have a 510 pin that protrudes at least 1-2 mm. Hits like a champ, it's probably my most used mech, even more than my one Authentic, the Vanilla.
