Personally Recommended
What sets these bottles apart from some of the others is the wide lid. Not only can you see inside to make sure it's clean, but you can drop ice-cubes inside to keep your water, juice or soft drink cooler for longer.
As the sponsor of the Central Coast Triathlon Club and the wife of a mad cyclist, we soon discovered the 600ml miniTANKA fits perfectly in to the drink cage on a bike, so it's perfect for those who like to cycle. None of our other bottles fit as well as this one does. The stainless steel in these bottles is just a little thicker than most, which makes these tougher than most, ideal for those tough 'boys' who like to toos things around and get grotty and not look after things!
All lids are interchangable and they can be purchased seperately if you want a spare, lose one, or would like different lids for different occasions. An adaptor lid and Avent Easy Sip spouts can be purchsed as an accessory and turns any of these bottles in to a sippy cup for a child. While we can't see a child lugging around the 1.2 litre bottle, the 350ml and 600ml sizes are ideal for toddlers and young children.
When you stop and look at the fact that it takes 10 litres of water to make a 1 litre toss away bottle, when you take in to consideration that it only takes a few days of replacing bought bottled water with your ECOtanka bottle to cover the cost, why wouldn't you buy one?!?!?
TESTIMONIAL FROM A CUSTOMER
The ECOtanka sippy cup grew up with my child. What a great saving! My daughter used the avent sippy spouts when she was younger, then as she outgrew them, we switched her to the sports lid. The avent spouts are only supposed to last 3 months, but I've seen 8-9 months out of mine and they still don't have any marks on them.
