I just got mine today so I can't speak to longevity but it came fully charged so I got to put it right into service. It's tough, super heavy duty and can really haul a half ton of stuff. I've filled it with firewood and also sand and gravel and it hauls it up a hillside no problem. The tires are spectacular, they dig in nicely and the thing has tons of power and torque. There are grease fittings everywhere! The fast speed is a nice brisk walk. Glad I didn't get the hydraulic dumper cause the gas shocks and manual release is quick and easy. Assembly was a breeze if you watch the video. Really glad I got this dumper. I think it's going to make my life a lot easier.

I shoveled about 30 cubic yards of dirt into this dumper and unloaded into roll offs within the first 10 days of arrival. The battery arrived fully charged, and I haven't even had to charge the battery once. Amazing workhorse. Completely satisfied with this purchase. An extremely well-designed tool. The only thing I would add is a second handle on the right to lift the dumper load when in a cramped space on the left. Besides that, I have no issues.
Customer service is excellent as well. I needed a replacement part, and Alan helped me by sending the part no charge with expedited shipping. I really appreciated that. Thank you.

We actually converted your battery powered wheelbarrow. We added a 26 gallon water tank, retractable 25’ hose, and installed a 12v pump which allows me to water my large flower garden.
You wheelbarrow has allowed me to continue enjoying my flowers which I was just about to quit because I could no longer carry so many buckets of water. Just a suggestion—if you could add power steering to this, it would be even more useful to me!
Thank you for helping me!!

I am in my mid 50's and my home is on a hill. A small one, none the less. I have a hillside flower bed that used 11 cubic yards of mulch and I stoned another hillside rose garden with 5 cubic yards of stone. I also heat with wood and need to bring wood up during the winter . This "big boy toy" has been worth every penny. My wife even commented it probably saved me from a heart attack not having to haul all of that up and down the hill with a traditional wheelbarrow.
