I am not a fan of these type of things, but they suit a particular need. I really dislike how some blatantly pry on the vulnerable, but on the whole i guess they get people out of a sticky situation sometimes.
I really do think APR is something that can't be used with something like this. They don't charge all that much but people see the APR rates and call them all names under the sun. these are not the type of loans you take out on an annual basis.
