This bottle is recommended in every way ... nice design and functionality shake hands. Absolutely to praise is the incredibly long holding time - although it is a bottle yes to there .... yet it does not happen very often that the drink also after 12 hours is still drinking hot (and cold coffee makes really no fun.! ) Through the rough surface structure, the bottle is still good grip even with wet hands ..... although this is unfortunately also the reason that you can not put in the dishwasher - but this is rather unimportant. The two attached, various bottle caps complete the offer skillfully. All in all a very good decision !!
