oPur oxygen bottle with mask

Brought this product, due to health problems, came this week and it is very lightweight, i was surprised by that and it has instructions on how to use etc. Verdict Very easy to use, portable easliy put into a bag and durable as well.I reccommend this only for emergecncy due to it,s 80.litres it holds and price wise is a little steep but worth it if you are having breathing differculities, asthma or any other problems.I use it due to smokers who like to smoke in front of me while i wait at bus stops and general out and about,(since this stops my lungs from working), they soon get the message not to do it i hope.Mask fits perfectly and lift cap on top off, press down and inhale easy .Instructions are in german and alittle in english with pictures.Defiantly would buy again in the future or maybe any chance of a refill bottle?

Absolutely rubbish it lasted less than 1 min and in my opinion a complete waste of money ,very disappointed had anticipated more for the no eyes it cost
