First off, let me say this nozzle looks promising with its stainless steel spout and swivel feature. The hook is a nice touch for keeping things tidy, and the 12 GPM flow rate sounds efficient.

I tried using it for transferring diesel between containers, and initially, it worked like a charm. The flow was smooth, and the seal held up well - no annoying drips or leaks. It felt sturdy in my hands during those first few uses.

However, here's where things get disappointing. After about two weeks of moderate use (maybe 10-15 transfers), the squeeze handle started acting up. It became increasingly difficult to operate, and eventually stopped engaging properly. For a tool that's supposed to handle frequent use, this durability issue is a real letdown.

The plastic construction might be part of the problem - while it keeps the price down, it just doesn't stand up to regular use like metal components would. That said, when it worked, the performance was solid. The swivel action made positioning easy, and the flow control was better than some more expensive nozzles I've tried.

Would I recommend it? Maybe as a backup nozzle or for very occasional use. But if you need something for daily or heavy-duty fuel transfer tasks, you might want to invest in a more robust option.
