Not to pleased with these piggy-back gas cans. In order to seal them, you have to put the spout back in, because the gasket is on the spout. If I put just the disc in, they leak. I really like the no-spill can, and I want to put one of those on the piggy can.
These cans don't make any sense, either you leave both spouts sticking out, without caps, or you put them back in every time, that's not going to happen. These things look like a Texas longhorn with both spouts sticking out. I was going to toss them, and just pour from the mouth.
Interesting info from nospill.com:
What's the difference between No-Spill's CARB cans and "non-CARB" cans?
No-Spill's regular (non-CARB) cans are very similar to our CARB compliant cans. After changes in CARB regulations effective July 2007, the only difference between a No-Spill® CARB compliant can and our regular (nonCARB) can is the special treatment of the can body for low permeation. By January 2009 the US EPA will require that all fuel cans comply with new EPA regulations (similar to CARB) so our regular (nonCARB) cans will be discontinued and No-Spill® will only produce our CARB/EPA compliant version which will include Child Resistance features required by CPSC in January 2009.
This may explain why they are more expensive. I'd imagine the crappy Blitz cans will be more expensive as well soon.
