OK – yes. It’s outrageously expenisve. We know that. Sigh. But wow – just imagine. A recharge lasts for a month. Fill it from any pond or spring, clean or dirty – it doesn’t matter. Press the button on top the lid – and seconds later, you’ll be drinking pure, safe water. Just like that. Recharge it from any USB port on your laptop or from a charger. The ONLY downside is the outrageous price. What do you think? Give us your feedback in the comments please. (Thanks for “bubbling this up” hahahaha, Caleb.)
