Have used the 1 litre bottles a lot. They work pretty well, though they do tend to shatter (yep, pretty messy and noisy when it happens) if the pressure gets too high (like out on a hot summer day). The last order was shipped (this is a first since I used to purchase at the retail stores until they closed) and one of the bottles was already broken. Overall, fairly happy, but wish I did have a retail outlet to purchase the bottles. They do also substitute a different brand occasionally, especially for the 1/2 litre bottles. They are not exactly the same size, but I like the swing tops better for the other brand. It has a solid rubber seal which I have never had a leak.
