which is great, because these tests are way cheaper
Works as expected, they did pick up pregnancy 4 days before expected period, didn't test earlier that cycle. The line was there no questions asked but it was much more lighter compared to FRER, for example, but it still showed up clearly, which is great, because these tests are way cheaper. And I tested at first 3 of these to make sure that I was not seeing wishful lines and then confirmed it with more expensive tests. In one cycle, I think, they picked up a CP because the lines were so faint and disappeared by the day of expected period. I tested also randomly in different days of cycle just for quality control. Stark white tests all the other cycles. Pay attention : They (not all but most of them) we're showing evaporation lines (greyish colour) when last urine run up the strip, they showed up for like few minutes and as soon as test was dry, there was no visible line, so I could not mix it with real line. Evaporation line would show up after timeframe, usually 30min to 1h or so depending how wet the test was, and go away as soon as the test was completely dry. So you have to be careful to read the test in timeframe, and my positive test lines opposed to evaporation lines stayed on test till today, they didn't disappear, and they are, in fact, pink, even if they fade out a bit when tests dry completely, but they are still visible when real lines.

DO NOT BUY- UTTER RUBBISH
DO NOT BUY- UNRELIABLE! If I could give 0 stars I would! Did a trigger shot to stimulate ovulation ready for iui the next day. Iui was carried out and I was admitted to hospital later that day due to unrelated health issues. Hospital did a pregnancy test which showed positive due to the trigger shot. I then tracked for the next 10 days to see how long the trigger took to get out of my system before we'd see a true positive. Every SINGLE one of these tests came back negative! The stress it caused me was unbearable, especially after a pregnancy loss back in April. Day 11 post iui I bought several boxes of clear blue early results, every single one was positive. I'm now 6 weeks pregnant and they are still showing negative! Absolutely disgusting the seller is allowed to get away with this. When I messaged the seller the conversation got very creepy, very quickly. Asking me when I was ovulating etc which I didn't find appropriate at all! They were sold to me as pregnancy tests ultra early, so that wasn't a necessary question. DO NOT BUY THESE!

Reliable and cheap
I like these as there cheap and reliable I buy these and use one or two a month due to being on contraception but like to still take a test a month just in case contraception has failed and they don’t break the bank like others do.

Great when ttc
These tests are brilliant for people who like to test a lot when ttc like myself. I did get a couple of ‘false positives’ a couple of weeks before my bfp, but I’m not sure if this was a chemical pregnancy as I had symptoms but the lines never got darker and were more grey than pink. I then got a shock 2 weeks later when I tested positive, I did a few of these to confirm and you couldn’t miss the line. Fainter than the control line but still clear. I confirmed with a clear blue digital that confirmed I was 1-2 weeks. I would just say with these, wait until you get a clear pink line before you get excited. For the price you can’t go wrong with these.

These do work
Bought 50 of these cheap tests, delivered a few hours ago. Tested 12DPO with 11pm urine.. and I got a very clear positive. Verified with 2 First Response and 2 Clear Blue with weeks indicator. I'm 40 and wasn't even trying 🙃

Awful shadow lines & faint false positives
Every test has a faint line even when dipped in water, comes up in colour and leaves a strong evaporation line. As someone that has been trying to conceive for a long time this was super disappointing. I wouldn’t recommend these at all

It worked for me!! Good luck ladies
The same day I bought it, the same day I got a positive. The dye stealer took a while to show tho. I am 6 weeks and 5 days currently today and finally got a dye stealer.

Picked up earlier than branded tests
Well after reading the reviews (even though these have worked for me previously) I genuinely thought I was getting false positives, the faintest line got ever so slightly more visible each day but I wasn’t convinced. I got absolutely nothing on 2 first response (6 days early test) but was still getting faint positives on these. Still sure they were dodgy I tried a clear blue digital…again nothing on there either. Gave up hope and put it down to a bad batch of these but to my surprise as a last attempt the day my period was due I got a positive first response at last. I wasted about £35 on branded tests and all along these cheap ones were right. I’ve been using them since to check progression (I have a complicated history with infertility and miscarriage so this is important to me) and they’re working great. For me personally these have worked on more than one occasion but I still doubt them every time!
