I don't understand them! Can anybody give me some idiot-proof information, please?
Some of them talk about replacement cartridges....some about replacement heads....some don't seem to mention either.
Lumea has a gazillion models and various comparison tables but none that I've found include all the different types.
How long (roughly) do x-number of flashes equate to...? I've found a model that does 400,000 flashes (compared to Lumea's 250,000) - does this represent a functional difference?
Argh, please help!
