My concept for it's use is primarily refilling tractors w/FEL's
Fill it up in the pickup bed, roll , put it in the bucket, store it. Put it back in the bucket, lift and siphon into the tractor.
I'd say elevation for gravity feed is key with these. I use a cheap 3 or 4 sheave manual rope hoist in my garage to lift mine.
The nozzle is definitely consumer grade. Mine has stood up for a few years of occasional use, but I'm the only one using it, and am pretty careful. I use it to store generator fuel, and for vehicle emergency fuel. I only put E0 in it. With the can elevated, I only use the handle pump to get things started to flow.
This company sells the pump handles in separate hose/can adapter kits I think; that would be one way to get a replacement handle off-the-shelf if needed in a hurry.
Plan on replacing the hose, unless they've really stepped up their game (doubt it, at the price-point). Mine was a hard plastic hose (likely to stand up to E15 etc....) and was unsuitable for my climate - I don't remember the hose leaking, but it kinked so bad that the flow was reduced quite a bit - I replaced mine with a decent commercial bulk hose. Shut-off valves seem decent, knock-wood.....
I wouldn't expect the nozzle to survive with a landscaping/maintenance crew, but if you are careful and can elevate the unit most of the time, then you may find it OK for light personal use.
One thing I can say about the nozzle - if I was away from home and my wife needed to fuel something ASAP, I'd sooner her use this nozzle than a regular gas can. The one time years ago she tried refueling something on her own (outdoor maintenance/chores has always been my domain) from a can, she managed to spill gas all over the place - didn't question the event too closely at the time (she felt bad enough), but I suspect she just didn't have the regular can nozzle tightened down well enough.
