I'll probably just use my Touch if I return my 2nd PW. The reasons is because I already have it.
I use the same big and heavy MightyBright 3-battery model clip on. It is really too big and heavy, so I'll need to find an alternative. I've tried other clip on but none were satisfactory.
When I had a K3 I used it with the official lighted cover. It was okay, but just. It wasn't really as bright as I would have preferred.
I'm wondering if the lighted cover for the Touch is any better. If so and they still sell them I might consider that option.
