Input: Gas spills easily from under lid. Three of us tried using it to verify, open/close lid again and every time it leaked. This is explicitly claimed as "no-spill". We were careful from beginning: (1) filled gas at gas station and verified that no single drop spilled while filling, (2) came home and tried to pour slowly into generator... started slow leaking from under lid. We were scared. Though generator was off... it was leaking few drops where generator usually is. So, we moved 15 ft away and filled into a tall glass and noticed the leak again. We cleaned up carefully, moved further and now, other friends tried... same result. Open/close lid, check twice, try again, same result. We figured this is unusable... Gas leak is Hazardous... fumes themselves are highly flammable. Guess what, returns not accepted on this product because... Gas cans shipping has certain constraints. It is not as simple as put in same box and ship. Safety, liability constraints makes returns more expensive than product itself. When Amazon was not allowing returns online, I could not figure why there is a no-return policy - I thought $ 35+ gone down the drain. However, when I chatted with Amazon.com support - they were understanding and helpful. They explained why shipping is complicated... advised me not to return product, but issued refund.

beware: spills/leaks, returns not accepted due to special shipping constraints
