Ovulation Tests

Hey ladies!! I'm looking at purchasing ovulation kits due to the fact that even though I get a period every month, my cycle is all over the place! It's really hard for me to figure out solely by charting when I'm actually ovulating. So my question is: how do you all feel about the dollar store ovulation tests? Should I stick with those or go for the more expensive ones? Thanks!
