my buddy and I love using these for a vessel to transport frosting. We usually take a few of these and a can of frosting on long mtb rides. All the flavors are great and easy to swallow. I prefer the vanilla myself. They do get kind of destroyed when they have been in the pack for a while, the crumbs are still good though.
The pump design is solid and I love how you don't have to take anything apart to pump up shredder or prester valves. I do wish it pumped a little bit more volume. It's also kind of pink but it sure is easy to see laying on the ground when you forget to put it back in your pack.
This chain deff gets the job done but you can't beat the easy install and removal of a sram chain with the quick link. All in all I feel they are comparable. Problem free as long as you take care of it .
