This bladder is very nicely made. The large opening makes it easy to fill and mine seals perfectly.
At 2 litres, it is fairly small so you will need to have daily access to drinking water to refill.
The bite valve has good flow and a nice strong magnet to provide a "base" that attaches to any 1" strap on your lifejacket or backpack.
If you plan to use the reservoir in different settings, you might consider buying an extra bite valve for each setting so you don't have to move the base magnet. I.e., I have one on my daypack and one on my lifejacket. It would be pretty easy to snap off the anchors on the base magnet if you moved it from one strap to another often.
