Four of our 5 vacuum insulated bottles were appropriate to be used with quandary. we have a tendency to tested the Klean Kanteen, SIGG, Hydro Flask, and therefore the Mira bottles. we have a tendency to additional boiling water to every bottle, and adjusted water levels till every reached 196°F, then checked on them in even intervals.
We removed the lids and checked temperatures with constant instant-read digital measuring system we have a tendency to used on the cold water test. quandary came back to temperature a lot of quicker than the cold water did, however these bottles performed in keeping with manufacturer guarantees.
hot water check chartLeak and drop check
A bottle that leaks isn't far more helpful than a lidless cup, therefore we have a tendency to tested every bottle for leak potential. Thankfully, none of the bottles leaked with traditional use and vigorous shaking or twisting, therefore we have a tendency to determined to try and do some drop tests to check however they get up to some abuse.
We stuffed every bottle to seventy fifth capability, then born it from standing position 3 feet from the bottom on its bottom, then yet again on its prime, and at last we have a tendency to pushed it off a table regarding 3 feet tall.
Surprisingly, all bottles remained watertight once being born. All chrome steel bottles damaged to a point, and therefore the uninsulated steel selection damaged the worst, inflicting them to wobble once placed on a flat surface.
We expected the game bottles with apparently fragile flip caps — just like the Embrava, below Armour and therefore the vacuum flask — to interrupt or a minimum of leak once they were born, however they failed to. throughout one drop, the Embrava’s lid really shifted off the cap threads a small amount and took some force to unscrew — nonetheless it still remained watertight once being substitute on.
While dropping the glass bottles, we have a tendency to were bracing ourselves for shattered glass all over with every drop, nonetheless no bottles ever shattered. The polymer sleeves did a decent job of interesting the drop impact.
