The first thing you notice about the XROS 4 is how premium it feels β especially for a $30 device. The body is made of a zinc-alloy frame with a smooth matte finish that resists fingerprints well. It feels solid in the hand, with zero rattle or flex.
At just 45 grams and barely bigger than a disposable vape, it's incredibly portable. It fits easily in any pocket, purse, or even a jeans watch pocket. The rounded edges make it comfortable to hold for long vaping sessions.
The OLED Screen: A Game Changer
The biggest upgrade from the XROS 3 is the 0.69" OLED screen on the front. It's bright, crisp, and shows all the important info at a glance:
- Battery level (percentage)
- Current wattage
- Resistance (Ξ©)
- Voltage
- Puff counter
- Charging indicator
Compared to the XROS 3's simple LED indicators, the screen is a massive improvement. No more guessing how much battery is left or what wattage you're at. Everything is clear and readable, even in direct sunlight.
Controls
The controls are simple and intuitive:
- Fire button: Top-mounted, click to vape. Also used for power on/off (5 clicks) and menu navigation.
- Up/Down buttons: Below the screen, adjust wattage. Also used for menu navigation.
- Airflow dial: Bottom of the device, rotates to adjust airflow from tight MTL to loose restricted DTL.
The button placement is good β the fire button is easily accessible with your index finger, and the up/down buttons are where your thumb naturally rests. The buttons have a nice clicky feel with good tactile feedback.
Pod Connection & Leak Resistance
The pods connect magnetically and snap into place with a satisfying click. The connection is solid β the pod doesn't wiggle or feel loose at all. There's a small lip at the top that makes it easy to pull the pod out when you need to refill or replace it.
Leak resistance has been excellent in my testing. After two weeks of daily use, including carrying it in my pocket, bag, and even a car cup holder in hot weather, I haven't experienced any leaking. Vaporesso has clearly improved the pod seal design over previous generations.
β Bottom line on build quality: For $30, the build quality is outstanding. Zinc alloy frame, OLED screen, solid buttons, magnetic pod connection, and zero leaks. It feels like a more expensive device.
