Most helpful critical review
A good product, let down by a sticking cap and noisy hissing.
on 15 September 2014
I bought this bottle to filter the hard tap water at work and act as a reminder to drink more water every day.
The reminder part works a treat; I now drink 2-3 litres a day, so I'm very hydrated.
Sadly, The Bobble has enough problems that I won't be buying any replacement filters for it. The bottle itself is fine; despite other negative reviews, I've never found it a problem to squeeze the bottle slightly and get water out of it. I will agree that sometimes it feels like it's on the verge of cracking and I wonder how long it will really last.
The main problem is with the filters. I'm on my second one, having followed the advice to replace it every 150 litres or so. When new, they are lovely - the pop up cap seals well and is easy to operate. After a couple of weeks of daily use, however, it's now so stiff that it doesn't easily pop up and in some instances I've had to grip it with my teeth and yank it up - not ideal for casual drinking. Also, as it's sealed, when you've finished a 'slurp' the air hissing back into the bottle makes enough of a background noise that my work colleagues are starting to notice. Drinking water all day is a healthy exercise but the constant comments from those I work with are making me think twice every time I drink - and that's not good.
The bottle was left in the boot of my car on a hot day and has got some blemishes where it was next to something else hot - and now it's slightly lopsided. Mind you, I would imagine the manufacturers wouldn't expect it to be stored somewhere hot so I can't really complain about that.
Overall, it filters well, and is dead easy to use, but the sticking cap and the hissing noise are enough to put me off. Healthy living has it's price and I'm prepared to pay for the product, but not the hassle of daily use!
