Value matches purpose
I do not like to use hydration vests (personally) so I have a belt and the 500 fits perfectly in there. This is a plastic product and used regularly so I guess it will start leaking at some point but overall nice product.

Works well.
This was to replace like for like, the old bottle still works but after 2 years is a bit grubby. The bite valve seems better on this one, more water comes out. It could do with a captive spout cover for when in a bag. I hope this lasts as well as the old one.

Really good for a little hydration
I generally run 5 to 15km and this is perfect to take a little hydration with me. Fits in my small chest running vest and east to use with the king straw.Came with a tea bag inside which had removed that plastic smell, no aftertaste either.Great value and ideal.

Perfect for what I needed
I was a bit worried it was going to leak based on some other reviews but it doesn’t. I’ve used on a few runs, you simply bite the tip and suck or squeeze to get the water out. I like that you don’t get air in so the water doesn’t slosh about as you’re running. It does taste a bit plasticky but I've added a bit of lemon juice to the water to take the edge off.

Leaking!!!
The media could not be loaded. Was really disappointed that one of the flasks is leaking and is therefore not usable! And it leaks a lot, no matter how tight you screw the cap on.
