Lezyne Mega XL GPS.
The longest GPS battery life in the roundup with a crisp black-and-white display readable in any lighting at an accessible $199 price point.
The Verdict.
Gavler Meta-Score
“The Mega XL GPS is for riders who want a reliable data recorder with unprecedented battery life at an accessible price. 48 hours of GPS means you can ride all week without charging, and the monochrome display is readable in conditions that wash out color screens. It's not a navigation device — it's a recording device. And it does that job better than anything else available.”

Global Critique
“The Lezyne Mega XL is one of the best computers you can buy — I don't know that there's another computer that offers this much functionality for the money.”
“The 48-hour claimed battery life is more than double anything Garmin or Wahoo offers; in three months of testing I only had to charge it once.”
“The maps are essentially an overlay — they don't display street names like those on Garmin, Wahoo or Sigma computers, and Bluetooth data transfer is slow. But these are only minor chinks in the armour.”
“Budget goodness: the Mega XL packs in features that punch well above its price.”
