I take my UNI 3.0 everywhere - from the office to weekend hikes. The lanyard hole is genius. I clip it to my bag, and it's always within reach. The adjustable chamber fits all my carts perfectly, no rattling at all.

I was tired of blind-guessing temp settings on twist batteries, so I gave this a shot for the display alone, and it was SO worth it. The screen makes everything so much clearer, and the voltage control is accurate. Feels solid in the hand, not cheap or plasticky. I've dropped it a couple of times, and it's still running like new.

I like being able to fine-tune the voltage. Lower settings keep the flavour clean, higher ones give thicker hits when I want them.

Picked up the UNI 3.0 a couple weeks ago, and the way it grips each cart feels surprisingly solid. Tossed it in my jacket pocket all day, no rattling, no leaks, nothing. The preheat feature kicks in fast, which helps when I'm stepping outside for a quick hit in the cold.

At night, I sit on the balcony and keep the Uni 3.0 beside me. Lowering the voltage yields a mellow, soft draw that's perfect for unwinding. The animations on the screen are a cute touch - they make the whole experience feel calm and almost cozy.

I use a lot of terp-heavy oils, so the voltage range was a big deal for me. Being able to drop to 1.8V for flavour or go higher for big clouds makes the UNI 3.0 super flexible.

I wasn't sure I needed another battery, but the UNI 3.0 really surprised me. The build feels premium, and the little details make a difference, like the 15-second cut-off for safety and the fact that it handles wider cartridges without any wobble. The screen is bright and easy to read, which isn't always the case on small devices like this.
