Yep. This topic actually made me consider one for the first time But I forgot to say before, I haven’t used one, so I don’t know how easy or hard it is. So you may want to get the opinion of someone who has direct experience before you buy one.
But from my point of view it does look like a big help. It’s just that some people buy them thinking it’s magic and get disapointed when they find out they still have to put in a little effort. So, yeah, for laziness it seems like it should really help, but not for total lack of motivation
