Lightweight, easy to use, 2 rechargeable batteries (and charger). I used it to cut about 200 linear feet of tree limbs - ranging from 1" to 8" in diameter - into 15"to 18" lengths. I had to recharge the batteries several times - but that was no problem, as I had to recharge myself every 15 minutes! [I am an 82-year old man, so a beer and pee break is needed every 1/4 hour]. The saw stops if it gets too hot, but you can let it sit for 5 minutes and continue. The manual does not give clear instructions on how to adjust the chain's tension. But there is a small cross-screw below the blade for that. The unit comes in a handy plastic carry case, with a spare chain. The chain I used is still as sharp as when I started. The carry case also includes is a pair of adjustable protective glasses and gloves, and the tools needed to adjust tension. A great little saw. I recommend it - especially for the price.
