Wondfo pregnancy tests reviews?

After several months (and more money spent than I care to admit) of using frers, clear blues, and dollar store tests, I finally caved and bought the 50 pack of Wondfo pregnancy test strips. The reviews seem to be hit or miss. It seems like there are some bad batches out there with complaints of false positives (but they seem to be an older lot). Any ladies out there have luck with Wandfo? Any advice or comments are greatly appreciated. I'm just afraid to get my hopes up.
