Best chainsaw I've ever had, and i have had and used them all i used to do right away work for GA Power and EMC way back, I've used every brand of saw you can think of, despite what you see and hear on YouTube and other videos about products it runs great cuts great, not even a half pull on rope it fires right up I've been cutting over 24" pine with fat lightered center and it cuts like butter , I do recommend replacing the stock factory chain its deasent but has a 2 to 3" gap / skip in it where put together, Oregon chains are really good.

You cant go wrong with this saw.

Leary because of price point, but I only needed a saw for home use. I had a 70 foot tree cut down and they left me with some very large pieces that needed to be cut to fireplace size. Ordered the SENIX 20 18" four stoke motor, added gas, chain oil and the engine oil that came with the saw. Fired up and cut for 3 hours straight, did not faulter!! idled great without shutting off, easy to handle and lightweight. I would recommend this a to everyone needing a light duty big saw. Cleaned it up, put in the box and its ready for the next job.

Best bang for the Buck !!

Better than anything in its price range.  Not as goon proof as a two stroke saw but just as good as anything I’ve tried in the similar power range. No issues with needing tuning or anything. Solid and reliable. Weight is good for me and maneuverability was above par.

Best saw for the price.

[This review was collected as part of a promotion.] Really really good chainsaw. Just takes a bit to get used to. When you do, not a better chainsaw out there.

Great buy

Great domestic chainsaw! Gets the job done. Great instruction manual and safety tips included. Best price anywhere. Came through in my time of need. Salute! 💪

unbelievable how this machine works. quiet not smokey at all. good cutting. I'll enjoy this for years

Good power, cuts good. Four stroke engine oil leaks unless you tighten with a wrench. Doesn't run as long as they say. Small fuel tank. Low noise level and no smelly exhaust.

Purrs like a kitten!

For light use only
Broke the handle on the second pull.
Chain is poor quality 
It's start real good
Runs hot if you force it to much.
Check the oil every time you refill you gas

For light use

Saw works well, only complaint is the chain lube leaks out. Other than that works as designed

Gas saw

extremely hard to start and keep running, lacks power, stops running once the engine consumes 1/2 tank. spend more time on bench than cutting wood. only runs for 5-10 minutes before it shuts down and requires service. not reliable.
