👀 First Impressions
Right out of the package, the TasteFlex Ultralock feels:
- Well built and small, fits in the palm of your hand with a clear tip to track juice levels.
- Sleek design that is comfortable in the hand and easy to slip in and out of your pocket.
Design-wise, it’s:
- The display is straight forward with just a power display and graphic.
- Button for Smooth or Boost mode
- On the bottom there is a USB-C connection for charging and an airflow adjustment that is pretty much either open or closed.
First impression: Well built but not heavy and a nice way to track juice levels with the clear juice compartment.
🌬️ Flavor Performance
Flavor is everything with disposables.
With the Sour Apple Ice, here’s what stood out:
- Inhale: Tangy apple
- Exhale: Iced, sweet, sour apple
- Sweetness level: Medium
- Cooling (if any): High, but not overwhelming
Overall:
- When they tell you this is sour apple, believe them. It definitely leans into the sour and tangy flavor profile.
- Just the right amount of ice for me, your milage may vary
Verdict: The sour apple ice flavor is spot on.

👍 What It Gets Right
✔ Solid design

✖ The sour flavor can be a little much after heavy use

🪑 Final Verdict
The TasteFlex Ultralock is very well built with a good flavor profile.
The flavor is good for those wanting something sour and tangy, with just the right amount of ice. The battery was where I was disappointed. I’ve tried two of these devices with different flavors and while this device was very unpredictable with battery life, the other performed much better. Maybe I was just unlucky with this battery. A few times I would grab it for a puff and it was dead after not using it much during the day starting with a full charge.
