Peel-A-Way Paint Remover For Latex Paint: Any Good ?

Have to remove some several year old (probably latex) paint from a concrete foundation.
Has anyone ever tried anything similar using those Peel-A-Way paint remover products ?
Any good ? Thoughts on ?
Which one specifically did you use ? Was it on latex paint ? They sure seem to have a lot of different types.
Any other brands/types that might be better ?
Thanks, B.
