SUPER IMPRESSIVE - It got here 2 days early. The setup was straightforward without problems. I assembled it and charged the battery same day (I had to run out and buy chain oil - required). It cut through downed trees easily and, relative to gas powered it was quiet as could be.

I thought I'd be returning this, but it's proven useful several times when I flooded my gas saw. Cut up two Aspen and a pine (rounds) before the battery died. as far as the chain jumping off, you just have to watch your angles. I've had it happen a few times but I'll always take this thing with me when I'm cutting. Even handles gamble oak no problem. -Matt A.

I've only used this to limb and buck one large tree that had fallen. Previously I had used a Craftsman gas-powered chainsaw for many years. The Senix saw was surprisingly powerful - as powerful as my gas saw. It was MUCH, MUCH easier to start (just hold down the button and lever) and it felt safer to use because I had no hesitation to stop it frequently and put it down while I re-set my position or moved cut debris out of the way. One battery charge was enough to limb and buck about 2/3 of a large (18" diameter, 25' tall) fallen tree down to 1/4 of a charge (the recommended stopping point). By then, I was ready for a rest

Always test the blade oiling function on a piece of cardboard before using. If it is stored in a cold environment it may not lubricant the chain and damage the chain. Best chainsaw I've ever used. Battery lasts along time. Cool battery down before charging.

My only knock is that the chain is one size fits one. You've gotta use the specific Oregon nano chain it ships with. Battery life, cutting up a 24" 10' overturned tree, pretty darn good.

Saw is powerful and cuts very well. I would give that 5 stars. The 3 star rate comes from the weight. The specification sheet on the web page gave the weight as 7.7 lbs. but that does not include the battery. Attaching the battery effectively doubles that, making the saw quite heavy. It is a good saw, but the spec sheet is not accurate.

The chainsaw runs well, cuts well and dependable. The battery only holds a charge for 20-30 minutes of continuous cutting, yet takes an an hour to recharge. This means that even with two batteries your limited to one hour of cutting. Great for minor work and or an old person that needs dependable saw. Not for any sort of heavy cutting load. However, for light cutting and pruning then the saw can be excellent.

Battery broke within eight months of extremely light usage. After one week of no response from Senix warranty dept., I'm posting this one-star review.

[This review was collected as part of a promotion.] I was so excited to be able to carry a chainsaw anywhere and not be tied down to the corded ones that I previously owned. I followed the instructions to put it together. Charged the battery overnight. Added everything that was requested. And when i finally wanted to use it, the exclamation mark kept on showing up. I did notice that the battery slot is flimsy at best and i tried to push the battery in farther until it couldn't go any farther but still nothing. I tried everything but nothing seemed to work. Very disappointed.

[This review was collected as part of a promotion.] I would have rated this chansaw very highly. When I initially used it it cut very well. I mean I was really surprised. Sliced through logs like butter. However, after about an hours usage the chain began to slip off, and finally to the point that the saw was completely unusable. There is a small hole that I believe fits into a pin when the cover is seated correctly. That hole and pin would not line up, thus the blade and chain were not straight and the chain would kick off. i tried numerous time, but to no avail to realign the two together, but to no avail. I could not move the pin namually although it runs along a slot. It may be part of the chain break mechanism. Either way, the cover no longer lined up. I need to return.
