Bests & Worsts Reviews from Amazon

I am giving this cup 5 stars, because I could not give 4.5. the only reason its not a 'perfect' cup for me is that like others said, the cover does inded let the smooth plastic cup slide out pretty easily, BUT...THAT IS TOTALLY EASILY FIXED by simply putting a wide rubber bad around the mid section of the cup, then putting the fabric cover back on. very tight then. I personally do not need long lasting thermal protection, so this is great for me, but if you stuff to stay super hot or cold for very long time, you need to spend more $, but i'm your avg joe, and this will hold my coffee just fine as long as I care to drink it inn the camping morning. some things are worth the $, with simple tweeks, and this is one. and all you need, is a wide rubber band. Don't permanently glue it, that ruins the fabric for cleaning, simply put the rubber band on, and it works great, but is still removable. Its all you need to counter the slipperiness of the plastic.
