Opinions on digital ovulation thermometers ?

Hi ladies , has anyone ever tried the ovulation basal thermometers ? If so , how did you find them . Were they accurate?

I’m struggling to be consistent with the strips as I have a very busy lifestyle and my memory is terrible . which obviously is making it hard for me to determine when I’m ovulating and when I should be baby dancing etc and wondered if it’s worth investing in the thermometers ?
