Pros:
- It's main value is it's ability to upload data to a pc.
- Has a complete range of features.

Cons:
- Bulky. It looks like a wristwatch, but it's as thick as 4 or 5 wristwatches stacked on top of each other.
- It only displays 2 quantities at once. So if you want real time info you'll be pushing buttons constantly.
- Temp, Alt and Power functions are inaccurate.
