The best cordless vacuum is the Dyson V8 Absolute Cord-Free Vacuum. This vacuum sucks up dirt as efficiently as a corded vacuum. It has a good battery life (about 30 minutes). It requires no vacuum bags, and it’s easy to clean.
I’ve been reviewing water filters for about 16 years. One of the best filters I’ve found is the Aquagear Water Filter Pitcher (made in the USA). This filter has been certified by ISO 17025 accredited labs tests to remove lead (97.5%), fluoride (90%), chlorine (99.99%), chromium 6 (99.87%), mercury (99.6%), trihalomethanes (99.99%), DDT (98.8%).
The Olympus TG-4 is the most durable waterproof camera currently available. This 16 megapixel camera can be submerged to depths of 50 feet (15 meters). It can survive being dropped from 7 feet (2.1 meters), or being crushed by a 220 pound weight (100 kg). The camera is also freeze-proof to 14 degrees Fahrenheit (-10 C). But what sets this camera apart from other tough cameras is the quality of the pictures it takes, and its quick response time.
