Be aware that there are counterfeits being sold under the Wondfo listing on Amazon. I have used genuine Wondfos for years and they have been awesome - accurate, cheap and my doctor has given them the ok. I received a new batch this past week that didn't say Wondfo on the front and had blue handles on them. I usually search to see if there is anything re: the lot I received and I found a lot of people complaining about both false positives and negatives with the counterfeits.

After searching, it seems that Wondfo has alerted Amazon to the issue, but Amazon has not pulled them. Wondfo has been contacted by other customers and I found that they have released a list of approved distributors. I just searched for one of their approved sellers and re-ordered the pregnancy test strips while also submitting to Amazon that I had received counterfeits and expected a refund for that order.

1st of all, these are great. I've used tons of them. I've never, ever had a false positive or even an "evap." These registered positive (albeit faintly) at 10 dpo, a day before 1st Response Digital Gold was positive. They are as good, if not better, than the $20/2 pack HPTs I'd sell you if you walked into my pharmacy.

For women who keep testing after getting a positive: these tests do take quite a while (many days) to get dark (as dark or darker than the control line). This was worrying me, so I decided to do an experiment (despite what you've read, the lines SHOULD get darker over time). I peed in a cup and took a test. Then I diluted it 1:1 with water, and took a test. Then I diluted that 1:1 with water AGAIN and took a test. All three were EXACTLY the same. All positive, but not any darker or lighter. This means that, at least within this range (about 20 dpo), a four-fold difference in HCG will not result in a lighter or darker test. This was very reassuring. These do get darker, but much, much more slowly than other tests. Do not worry too much about them not getting very dark quickly.

Now, please let me dispell the FMU (first morning urine) myth, which drives me crazy. It's just not true. Here's why: we've been told to use FMU (or, at least to hold our urine for a long time) for better results. Not true. HCG blood levels in early pregnancy increase with time. So, your blood level last night was lower than your blood level this morning. The FMU in your bladder this morning is a mixture of last night's urine, this morning's urine, and ever thing in between. The "old" urine from last night has a lower HCG that this morning's urine and is therefore "diluting" the HCG.

For those of us who just can't resist the urge to test over and over every cycle, these pregnancy tests REALLY save on money. I haven't had any of the false positives that some people have mentioned. I did have an evaporation line once, which can be confusing. When in doubt, use another test. They're cheap enough that you can afford to! Also, the tests I received are different than what's shown in the picture. It's a different shade of pink, and the handle says HCG over and over. The packaging says OneStep on it. But I was prepared for this by other reviewers, so it didn't bother me. Apparently they are still manufactured by Wondfo.

Update-- It took us 7 months, but we finally got our BFP! These strips were able to show a positive result at only 10 DPO, and they showed a clear progression with the lines getting darker as the hcg increased. I'm very happy with them. :) I added the series of tests to the customer images.

After buying a batch of 25 and going through them in a single cycle, I bought these. The packaging is identical to the "pink handled wondfos" I bought before, but the handles are a pale pink with 'hcg' repeated across it. Everything else is identical. I actually prefer solid handles as I can write on them and see what I wrote easier, but the important bit for any pee test is the result.

And these are very similar to the ones I had before. The control lines are a consistent intensity from my previous batch of tests, and since I'm pregnant, the test lines are about as much darker as I'd expect.

This came with instructions, which the other ones did not, not that it's rocket science. See photos for a quick how-to. The price is, of course, excellent.

There are still no evaporation lines anywhere (defined as lines that show up when the test dries, usually outside the testing area). These are fast, though the positive takes longer to show up than the control line, but I'm still early yet.

There has been a little streakiness on a few tests: These average slightly more dye per test than the pink handled ones, but as you can see from my pictures, the results are quite consistent.

You'll need your own Dixie cups, but that's a pretty trivial expense.

Definitely a recommend.

I've compared the plain pink and pink hcg handles in the same sample and the results are nearly identical, and both perfectly functional. Don't worry about handle color!

UPDATE: The gals on FertilityFriend and I have been doing some experimenting. Some people may know that dipping a pregnancy test directly in cola or apple juice can create a "positive" test (not just on this brand).
