Bests & Worsts Reviews from Amazon

It's vacuum insulation is astonishing... but it becomes useless if the lids are not well designed. The 22 oz version comes along with a stainless steel lid and a flip lid. The stainless steel lid provides vacuum insulation and is leak proof, both of which are great BUT when it comes to usability it fails: the hole for drinking is too wide, so forget about drinking while on the move if you don't want to splash water all over. The flip lid solves that problem, the drinking hole is small so you can drink while on the bus or walking BUT it's not vacuum insulated nor leak proof, so forget about cold drinks (the lid sweats A LOT) or putting the bottle in your bag (it will leak). What's worse, I contacted Simple Modern about this and they just replied the do have a lid that is vacuum insulated, leak proof and has a small hole for drinking, so I could proceed and buy it. To be fair, they gave me a coupon so the lid would be free when buying from their webpage BUT I would have to pay for the shipping. I don't live on the US, and every buy I make comes with extra taxes. I decided not to buy the extra lid, cause I think that when you buy a product, that's it, you shouldn't have to pay extra in order to rectify deficiencys.
