Do Sunscreen Wipes Work?

Has anyone used the sunscreen wipes? Or do you think it's a waste (makes extra trash and pricey)?
They seem really convenient for the purse/diaper bag and even for daycare. Any particular brand you like?

TIA for any advice and/or recommendations!

Not sure they work. Many of them received bad ratings on the Skin Deep Cosmetic Safety database.

I think this is pretty darn handy for the purse:

I got one at Target last week.

I tried the wipes a couple of years ago and the idea is great but I wasn't that impressed with the ones I tried (can't remember the brand).

I hadn't seen the CA Baby sunscreen stick the other poster mentioned but that seems pretty handy for the diaper bag. Might have to try that.
