Pesky portable nebulisers

Hi can anyone recommend a good reliable portable neb. I have brittle asthma so its real scary when it won't work, just got new one at beginning of Feb and it won't work either from battery or socket. Have got heavy old noisy reliable one but it only works from socket and is sooo heavy to cart about. Thank you. (Its a Sony Green model - the one that keeps conking out)

Omron micro air or pari uni light mobile.

Micro air is completely silent but the uni light mobile is much quicker. I personally orefer the uni light because it is quicker.but in certain situations the micro air is the more suitable neb.
