This mower seems well made and has a Briggs and Stratton engine on it .Assembly was quite easy and it started right up.

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. ⭐️⭐️⭐️⭐️⭐️

Good light duty lawn mower for the price. Came with the required oil and was simple to assemble the handle into position. They have knobs so no tools are required. Having the option of side discharge, mulch, or bag is a nice feature. Poured in the oil and some gas and fired right up and cut my yard without any problems. It has a decent quality Briggs and Stratton motor that had plenty of power to cut my St. Augustine sod lawn without struggling. The only issue I had was one of the adjustment handles for the wheels was bent in shipping or packaging and I had to remove the wheel to get the adjustment bar bent back into shape. For me this wasn’t difficult, but could be a problem for someone without the tools, etc to complete the repair. Update: After sitting for the winter a couple of months, the mower started first pull and ran fine. I use Sta-Bil fuel treatment in the gas. Without fuel treatment the ethanol will destroy the carburetor.

Product was assembled incorrectly at presumably the seller’s warehouse. The back wheel height adjuster lever was installed outside of the entire zone of heights, rendering the lever fully pinched between the wheel and the hood of the lawnmower. I immediately attempted to contact the seller and it was nearly impossible. They have the default with Amazon that returns/refunds simply aren’t allowed for any reason. After an hour of guessing and checking within Amazon itself (and selecting “other” repeatedly to send a substantive message) my message has not been replied to. Buyer beware, either this is a fraudulent company or they are near inept with customer service.

It’s a good one and cut quality is really good. Perfect gor small backyards. Speed is fine but a bit of noisy. We switched from an electric one and this one is definitely easier to use.

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.
