get monthleys, they are a lot cheaper, and i see no advantage of dailys, having used both.
I use specsavers own, pack of 3 with small case and solution sent every 3 months in the mail.
i see no reason to get the expensive ones, £13 a month i pay, and they are always fine, never itch or hurt, and i wear them for long days, like get up for lecture at 8am, put em in, go out that night and take em out at 3am, and my eyes still feel fine.
i think there are different monthley ones, mine i am supposed to take out every night and put in cleaning fluid, which people say is a fuss but honestly it takes seconds to do.
i have slept in them a few times though, if ive crashed at someone elses house, and not had a problem with them being in whilst doing this.
also i have had them on in the shower, which is fine, never swam in them though.
lastly i dont clean them in my palm either, shove em in the pot and shake, they are fine like this.
