I bought the original of Kickstarter and my short review will be on my usage. Specs and stuff you can get of the Interweb.
I had a MSR water filter which blocked as soon as you looked at it rendering it useless within a litre. I live in Scotland and usually rely on open source water with no real problems but had some odd tasting stuff from Lochs and with some foreign travel planned I thought I'd give it a shot.
Regarding the overseas travel I was conscious of the health issues around water but also the disastrous effect of plastic bottles and the relative expense and time wasted sourcing water.
I felt that this would be an ideal solution for UK outdoors and foreign fields and so far, after 4 years, I think I made a good decision.
It's cost is cheaper than the rufty tufty MSR types which do offer connectivity to Nalgenes etc but this is a simple unit that carries well and hasn't let me down.
I carry it instead of water bottles in the UK as water is so plentiful and when travelling (remember that?) I take it in my hand luggage and in my touring day bag as it carries 500ml and can be drunk from but I can refill at every tap I can find. I can also decant into other bottles on the hoof or back in the hotel room for the next day. No plastic bottles any more.
So far, Nepal, Egypt and Australia and if I lost it I would replace it straight away and have caused the purchase of Grayls by friends after they'd used them. Even borrowed by a travelling son who avoided much illness in Nepal that took out all his friends.
I'm that time no damage to the plastic and I added a carabiner to the lid to secure it to a bag.
Criticisms? Slowish to pump through but we're only talking long seconds not minutes. And small relative capacity as a vessel but it's a compact unit.
I've been umming and ahhhing over getting one of these..... thanks for the timely review!

Fair comment, the filters can be a little pricey, but it's worth putting into perspective how much you might use the filter. When I got mine, Amazon were doing a deal in which you could get a spare filter with your purchase.Only good for 250 litres before a £20 replacement filter required?
I bought the G3 in stainless and black with a purifier spare cartridge last year for just under £50 for the both. It sat in a drawer forgotten about until a couple of months ago. The only water i usually take with me is in a 1l canteen to make tea with. The spare canteen carries cognac. Anyway, there was a day in march when the temp hit 20c and i had used up all my water by nightfall. It wasn't too much of a problem as water gathering is never a problem ont moors but i wasn't suffering and couldn't be bothered to filter and boil. I decided to take my Grayl the next time, which i did. Having been extremely ill having once drunk untreated ditch water from the side of a road in Armenia i am very wary of drinking anything that doesn't come from a UK tap or a pet bottle. But having spent 50 quid and having read all the reviews i needed to put this to the test. I set up my camp close to a path back home so i could crawl back home if needed and went and filled the flask with stagnant and smelly water from a hollow. Just like a coffee press in operation and simple to use it provided me with just under a pint of clear and non smelling water. I was extremely apprehensive at first about drinking it and took a small swig. It tasted ok and i drank the rest over the next 30 minutes, with no ill effects. You have to have faith in your equipment, that it will do what it is supposed to when you need it to. My faith was reinforced by reading as many reviews as i could about this product. In the UK this allows for longer trips without having to visit human habitation to re up with water or take uo space carrying extra supplies of it. Make sure you get the orange purifier unit to go with it as the supplied grey colour one is just a filter unit.Does anyone have or able to review the Grayl Water Filter Bottles?
Not seen much about them but have access to them.
