Hellobee Boards

I like wondfos! I've found they're suuuuper sensitive...some people like that, some don't!

ETA: I've never tried the tests in your link. So they could be good as well! But no personal experience with any internet cheapies besides Wondfos

I used the easy@home brand from
eBay and got a ton. I used those for opks too. I bought another kind off eBay a few years ago too and they were similar. I feel like as long as they are the pink dye they're all very similar in terms of sensitivity, accuracy, and usage.

Had no trouble with that kind or wondfos.
