range that I can always charge to 100% — unlike other brands that told me it was recommended to stop at 80%, which consequently cut my real range from 600 to 480 by not being able to charge to 100%. I think that's something people should know.

I've done 6,000 km and I'm delighted. I haven't tried other EVs, but I'm thrilled with the BYD Atto 2. It's true I don't go on long trips — I do everything in the city and nearby, about 100 to 150 km a day — and honestly it's been great in every way. When I hit 300,000 km I'll tell you again. Haha
