It does what it claims. Carries gas and does not leak when you pour it. Purchased many of these cans, and happy every time.
I am 68, and have seen many kinds of gas dispensers over the years. I have spilled my share of gas filling up all manner of gas-powered devices. This is the best I have found so far. It is easy to get the can safely situated before releasing gas. You are able to let the mower bear the weight of the can before and during filling, releasing you from having to hold the heavy gas can awkwardly while trying to see the gas level in the tank. My only complaint is the storage cap over the nozzle tip is tight and it is difficult to gain purchase to remove it. I may cut mine off. Otherwise I would give it 5 stars. I have had it about 6 months, and see no reason why it won't function well for many years.
We have been mowing commercially for 30 years and averaged 1000 gal. of fuel per month with no problems. When the government decided to get their fingers on gas can design my life took a turn for the worse. The NO-SPILL cans are definitely the best that are currently available.
