Class bottle; have now for three weeks always on the job! The glass bottle is stable, the plastic lid seals tightly, the cleaning is also simple, the design anyway beyond doubt, ..the water already contained tastes quite nice, but I'm also quite spoiled in OWL, what good management and As spring water. ;) I use this small version and a 800ml variant as a receptacle for my sparkling table Sodastream water because I do not like the natural taste of plastic bottles and these also do not trust.
For the price 'ne strong buy recommendation! (..auch, Once you stupid happens to spend several euros for not even 'nen half a liter of water.))
----- ----- Supplement 23.06.2015 ..habe the bottle STILL daily at work! So far, no wear is observed. So to use even for prolonged use super.
