    • Easy starting
Easy starting. I travel for work so my wife mows the lawn. This is the 2nd mower in less than a month. I forget what brand the other mower was. My wife could not start the other one. This on starts right up for her and moves itself right along.

    • Great mower if purchesed on sale.
Great mower for the price I paid for this (200 less than current). 4 stars for Briggs & Stratton engine. I would stay away from china engines. 4 stars for power. 3 stars for bagging, grass. 2.5 stars for leaves- too much is not bagged and just blown around. 3.5 stars for mulching but doesn't do well in tall grass.. 4 stars for ease of starting. 3.5 for self propel. I definitely would by again for the price I paid but I would not buy at current price, I would go to Walmart or HomeDepot. ... show more

    • Worthless!
Worked three times on a small yard. Would not start afterwards no matter what I did based on the instructions. Bought it based on the reputation of the company making the motor. What a mistake! Don’t be fooled by the cheap price.

    • Outstanding Customer Service
The first mower didn't work. However, the customer service was outstanding. They sent us a replacement and it works wonderfully. It is easy to operate and so far we are very pleased.

    • Tough luck
The box the mower came in was mangled and wrapped in plastic tape. I had been tracking it's delivery. I saw it come to Lubbock It was a day early. I was alerted by UPS it was here early. I was excited. But then it went to Illinois. I watched it on the tracking window. They took 2 more days to get back to Lubbock. And I could see the torn up, boxed mower. Oh the mower was tough. It was wrapped plastic tape..The mower was ok, but the small parts were GONE! UPS' fault. A tribute to the SENIX Mower Though!🙂 And powerful. DLB of Lubbock Texas ... show more

    • Great Value for a Self-Propelled Mower!
Started right up after assembling and putting in the gas and oil. Runs like a dream with that Bruggs and Stratton engine. Our last mower with this engine lasted over 20+ years!
