What are the best OPKs to use?

Hi ladies!

I'm currently in my TWW and somewhat hopeful but thinking ahead to next month just in case I don't get my BFP.

I used the CBFM for about a year with no luck, took a break from opks this year up until this month when I decided to give them a try again. Well, I'm fairly new to Glow but piecing together that not many people like the CBFM and this is now paired together with my lack of success thus far and frustration using them this month (I clearly had two dark lines one day and the machine read this as High, not Peak. Never got a Peak and trusted the stupid thing so feel I may have missed crucial days to BD - also doing SMEP for the first time).

Anyway, sorry for the long back story! The point is, I want to continue with opks for now, but I'm ready for a change. So, can I use the remainder of my sticks as "basic opks" without the machine? anyone do this before?

And what would all you ladies say is the best brand and type of opk? I've read negative things about the smiley type too. I'm thinking basic might be best at this point, but would so appreciate your suggestions! Be as specific as possible, brand, how you use them and interpret, etc. Thank you all so much!!!
