This is my first electric chainsaw and so far I’m impressed. I charged the battery fully and ran the saw for about 30 min cutting up this pine tree and pruning other limbs. There is still 4/5 battery charge remaining according to the LED. I used the EGO bar and chain oil, it is VERY thick and sticky, and I’d say only used about 20 % of the oil in the reservoir in that time. I read concerns about seepage while not in use, which the owners manual says is normal. I’ll have to see if that actually happens. I was surprised at the lack of noise compared to a gas saw, it sounded “weak” but flew through the tree trunk with ease. If the saw and battery hold up over time, I will be very pleased with my purchase.
