There is some design flaws. Pump leaks. It serves the overall purpose which is to drain 10 gallons of oil in one effort. Pan on wheels makes it so much easier.
Not the most sturdy on construction. Casters are easy to guide under vehicles. Handle cheap and won’t hold up long. We immediately modified design. Overall it works well. Just keep in mind it’s only going to last if you do not abuse it.
I am not using the hand pump I just needed the cart so this review is not about the pump just the cart and its quality. I paid more for a junk plastic one this one is much better. Rolls nice good wheels. Overall very happy.
Easy to maneuver and works great. However the bracket that the handle for pulling the unit around attaches to cracked on the first use. Also the hand pump is vey slow.
