Review on Spout Flexible Universal Accessories Expandable by Mike Groover

I bought these after reading many reviews. I was expecting the product to be fragile but I knew I would be storing gas canisters in the shed and out of the sun so I decided to give it a try. They withstood any gas I could have. Now I have about 10 gas bottles and I used them all right away to replace my old spouts. do not leak, do not let steam through, plug banks well. I refill my glasses every time I use them. I live in Florida and always have plenty of backup gas for my generator. Since I use gasoline in my truck, I fill it up with my gas canisters. then I bring back all the empty glasses at the weekend and fill them up again. Each jar is used at least once every 2 weeks. I often put my hats on and off. I wasn't expecting a cheap product to last long with so much use, but they hold up really well. I will definitely be buying more to have on hand when I buy more gas cartridges
