Which CGM is actually worth buying?

I'm thinking of trying a CGM for the first time but I'm getting confused looking at all the options and prices.

I have Type 2 and I'm not on insulin. My main reason for wanting one is to understand what different foods are doing to my sugar and whether things like walking after meals actually make a difference.

Libre seems to be the one I hear about most, but I've also seen people mention Dexcom and a few cheaper options online. I'm trying to figure out the actual monthly cost too, because even if a sensor looks affordable, replacing it every couple of weeks adds up pretty quickly.

For those of you using a CGM, which one are you using and roughly how much are you spending each month? Is it worth using continuously if you're not on insulin, or would using one occasionally for a couple of weeks be enough to learn your patterns?

I'm Type 2 and not on insulin either. I used Libre for a few weeks mainly as an experiment. The biggest thing I learned was which breakfasts were messing me up. Some foods I thought were completely fine gave me a much bigger rise than I expected.

That's exactly why I want one. I don't necessarily want another device forever, I just want to see what my normal meals are actually doing.

Don't compare only the price of one sensor. Work out how many days each sensor lasts and then calculate what a full month actually costs. That's where the difference becomes much more obvious.

Yeah this is what confused me. I kept seeing individual sensor prices and then realised that's not really the number I should be comparing.

I use Libre and the convenience is what keeps me on it. I care more about whether I can reliably get replacement sensors every month than having the fanciest CGM.
