Fantastic mower!!! This eats through the tallest grass for me so quickly, compared to the whimpy electric one I had a long time ago. Doesn't eat up too much gas, and runs so well. The sound is somewhat loud, expected for a gas mower, but I don't care. Highly recommend it. Easy to use, powerful, and superior to Electric mowers. ⭐️⭐️⭐️⭐️⭐️

Reliable, easy to use and cuts well. Two years old and used each week in the tropics. Good size for most all terrains.

I purchased this mower last June and it has been amazing for the cost, light weight does a fantastic job mowing and evidently the manufacturer is local to me. Only issue I’ve had is the throttle cable broke but the mower has a 2 year warranty that I registered. I called their customer service hoping to get the part. Sounds like they don’t make this mower anymore or the part at least so they sent me a replacement mower at no cost. I even got an upgrade because the exact model was out of stock. Super easy and friendly customer service.

I received the lawnmower today, and I was immediately impressed with how easy it was to get started. The packaging was simple to open, and setup was a breeze—just tighten a few screws, add oil and gas, and you’re good to go. Assembly-wise, I’d give it five stars. The engine runs well for a 125cc motor. It’s not a high-end mower, but for the price, it cuts efficiently and gets the job done. However, I did experience one issue on first use: about 30 minutes into mowing, the engine started producing a bluish-white smoke, which is usually a sign of too much oil. I followed the manual closely upon startup and double-checked the oil level twice before restarting. It smoked again briefly, so I let it cool for an hour. After that, it ran clean, and I was able to finish my yard without any further issues. I’m hoping this was just a break-in quirk and not a recurring problem. Other than that, I’m satisfied with the mower’s performance. If the motor holds up like my last Briggs & Stratton, which lasted five years, I’ll consider it a great purchase.

Customer support is really, really bad. The frame for the grass catcher had a faulty weld and it broke on my first use. I immediately filled out the support request form on the Senix website providing all warranty information. I also emailed them pictures of the faulty weld and described the situation and provided a picture of my Amazon purchase. I purchased this mower over two months ago and after 10 attempts at getting this resolved, they are asking for all the proof/documentation again. Weeks can pass before I get a response, if I get a response at all. I'm beyond frustrated.
