5 amp battery died and a new replacement 2. 5th star will depend on its longevity. I am blown away on the performance of this saw. It is nice to have for stumps however. I don't get all the negative reviews.

Blue Max 53543 Final Thoughts
"The new saw is good."
Which came out after I got the Blue Max saw. This is probably because the motor gets too hot. It also cuts some surprisingly large size logs. I have several gas chainsaws 14-30ins. Most trees we're over 3 feet in diameter.
