Hi, I had a c-section and did use The Hydrant while in hospital, and can honestly say that unlike many of those who've posted comments - negative ones at that too - I did find The Hydrant to be very useful during my 5-day stay.
Although many people are saying that you could just as easily use a cup or sports bottle if you wanted a drink of water, the main point that I think a lot of people are missing is that The Hydrant is designed a) so that you don't need to reach anywhere to get it as the tube-like part that you drink out of has a little clip attached to it so that you can simply clip it somewhere. Having hooked the bottle on to say the side of your hospital bed, you don't stretch anywhere to have a drink of water. Yes, of course you can keep a sports bottle or bottle of water on your bed but how much water do both of these hold; b) to hold a large volume of water, so that you don't need to keep on asking anyone to pass or get you some water.
I doubt that some of the people on this post have had c-sections and therefore probably don't know what's like when one is in pain and to even get off the bed to pour yourself a glass of water that yes, as been put in the corner of your "room" towards the back, is a task in itself.
Some of the comments on here are totally unnecessary ie. if you don't like the product (which some of those who've posted a message hasn't even seen), why don't you just say that, rather than spending their time using words that are really not nice and beneficial to anyone, apart from making themselves feel as if they've been heard.
My verdict: thumbs up to The Hydrant, and however well it does, well done to the inventor of it for coming up with the idea to help post-birth mums, and others too.
