I have a Phillips Innospire Go as my main portable neb. Back in September I had to take that on my boat holiday on The Broads because boat power would recharge that but probably not run my motor machine (as my brother calls my mains neb!) Then the power was being odd so, to avoid issues, my mum got me a Microair U100 because they're battery powered. I was a bit dubious because when I had the previous model of Omron portables, it stopped working because the liquid etc would mess up the contact points. Anyway, this was great when required. It's been used 2-3 times every few weeks since the end of September - and the other day started turning off mid use. Not batteries definitely the mesh and contacts being swamped even though it's dried out after each use etc. So it's gone back.
Does anyone else struggle with the Omron portables or is it just me?! I know some people love them so maybe I'm just unlucky.
Thankfully normally I use my Innospire Go when not in the house otherwise I'd be panic buying!
