Obviously, all just in my opinion but... I bought a pack - never again! They were very thin and flimsy, and a good proportion of them leaked (and not just a little bit either). One of their selling points is that you can return any packs you don't use, but when I looked into doing so it would have cost around ?10. As you get ?6.66 back per pack, and I was sending two, it would have meant I'd only have got a few quid back. Not really worth the effort of lugging them up to the post office with a toddler in tow. I was given pretty short shrift by kiddicare customer services, and funnily enough my 1 star review never seemed to make it to the website! All just what my experience was like though..I'm sure others will have thought they were great!
