I have a cupboard filled with water bottles. We carry them around the house, out to the garden and throw them in our backpacks when we leave the house. There are many water bottles on the market that are made out of sustainable materials and a good water bottle that doesn’t leak or break is a must-have item. Finding an appropriate bottle for school turned out to be a challenge.

I wanted a cost-effective choice – under £10, ideally under £5 – if it gets lost or dropped, no big deal. Glass was out, my daughter doesn’t like stainless steel because they dent and hurt her toes when she drops it, which left us with the BPA, phalate and PVC-free plastics like Tritan and HDPE. We tried a few and she returned with complaints – the attached cap retains water that drips when she drinks, the open top lets through too much water, the screw top is hard to unscrew, it doesn’t look distinctive and cool.

One week later, she went to school with my bedside water bottle – a Bobble – and came home with a smile. It didn’t leak, it never spilt as she drank, it was easy to hold, open and drink from, it was surprisingly robust when dropped and did not damage her toes and she thinks it’s pretty cool. “Does it come in rainbow colours?,” was the only question and when I said yes, it settled.

We still have a Bobble in the water bottle shelf more than two years later because they’re excellent for travelling as well. We love the integrated carbon filter and Cass now never complains that the water tastes funny when we stay somewhere new. Bobble is an ethical and environmentally friendly choice for a reusable water bottle with the added benefit of having its own filter so that it can be filled up straight from the tap. Recommended.

There are a few things to note about it – it is a sipping bottle which is great for little kids, it’s not a good choice for drinking a lot of water quickly. Secondly, it does make a soft hissing sound after drinking – again great for little kids who seem to love it, but not so great when in an important meeting. Thirdly, it is not leakproof. It works fine in an external bottle holder pouch on a bag, but I wouldn’t throw it in next to my mobile phone to bounce around upside down. It is sturdy, yet soft plastic that makes it easy to hold, but when dropped, it scratched but hasn’t dented or broken yet.
