Most (if not all) gutter cleaning tools on the market today, just work if your gutters are 10 to 15 feet off the ground. The gutters on my home are 30 feet off the ground and this tool works like a charm! Imagine if a homeowner owned a shop vac tool and have 25 foot gutters filled with water.
Beer Koozies Do Help Keep Your Drink Cold -- But Not The Way You Think They Do. Turns out there's a scientific justification for beer koozies (those foam-rubber beverage sheaths the local radio station gives away at the county fair): They shield your drink against the droplets of water that form on the outside, which can put the heat on your drink.
But what separates the Yeti Cooler from all the freebie koozies out there (aside from the price) is that instead of foam and neoprene it's made of 18/8 stainless steel with double-wall vacuum insulation. It's basically a thermos for your can of beer that will keep your brew cold for a very long time.
