Review: Who would think a four stroke chain saw would perform as well as a 2 stroke of same size? - I have used a chainsaw most of my adult life including 3 years professionally. 4 stroke engine technology has improved to the point that this saw impressed me. Build quality seems good and the saw cuts like a champ. My previous chainsaw I used for 27 years for light duty around the house was the same displacement size engine (46 cc) but a traditional 2 stroke. This chainsaw builds power at a much lower engine speed and although it does not run as fast (probably 70% engine speed compared to most 2 stroke chainsaws), the cutting speed does not seem that much slower. This chainsaw was packaged well and instructions are simple to operate. Weight of this saw compared to my previous chainsaw is a small amount heavier, but is balanced well. Size of this saw also is small amount larger (engine assembly), but neither the weight or size seems to affect general use compared to my previous chainsaw. Overall I used this chainsaw 1.5 hours 1st use and have to saw I am a fan. The engine has enough compression that for me required I place on ground with a foot holding it when pull starting. It starts easily and I don't feel uncomfortable allowing engine to idle (a benefit of a 4 stroke is less likely to "load up" if allowed extended idle time) as I move/stack wood. Engine noise level is less especially at full throttle compared to most other chainsaws.
Review: Best chainsaw Ever! - This is a great chainsaw! Easy to start, four stroke, no more mixing gas and oil! Lower RPM but plenty of torque to cut right through a 10-in ash tree. I was impressed with how much gas it holds. At this price it was cheaper than repairing my old chainsaw! I like being impressed, thank you.

### ⭐ Absolute JUNK!
*by A***R on December 9, 2024*

Got this 18” chainsaw in January ‘24 and I just got around to use it. Ran it for almost 10 minutes before it sputtered and died. Made sure fluids were good and followed manual for troubleshooting. It would not turn over at all. In the process of starting the pull cord broke! Contacted Senix and it took them almost two weeks to respond with a email asking for the information and pictures that I already sent in the original email. Sent another email and never heard from them again. It’s been almost a month! Oh, they don’t answer their phone either! DO NOT BUY SENIX PRODUCTS… They are junk and customer service doesn’t exist! Get yourself a Husqvarna and save yourself from the insanity!
