Exactly what you'd expect -- it's a big, bad, sturdy, stainless steel reusable bottle.
I've only had water in mine but if you were to keep flavoured beverages in it (juice, etc.) they should not impart any flavour to the non-porous, stainless steel bottle. Very sturdy construction that should prove drop / smash / bash / crush-proof. I have lots of confidence in the deep, screw-top cap seal to have my bottle's contents not spill all over whatever bag I have this stashed in. The slim profile means this slides nicely into mesh side backpack pockets, bicycle bottle-holders, fridge doors, etc. Note that this bottle is not double-walled so it's not really designed to store hot beverages.
All in all, I expect to have this for years to come, which is what look for in products nowadays: things that last.
