Reliable
Great value pack of pregnancy tests. They provide reliable results. They are too small/thin to hold in a stream of urine, in my opinion. I use them with a plastic disposable cup. Would recommend.

Good value for money
I’ve used these for years for reassurance as I track my cycle naturally. They are great value for money and do the same as other tests just without the unnecessary plastic casing. These are particularly good during early pregnancy - you can take daily to make sure the line continues to get stronger without spending a fortune on plastic tests.

There are better options out there!
I bought these as it was a much cheaper option than the traditional branded tests which often don't detect pregnancy until later than you might like. The dip sticks they use at the doctor's office are very simplistic and accurate and cost next to nothing, so when I saw this pack with a 10mIU/ml sensitivity (the lower the number, the higher the sensitivity, the sooner you can test) I figured I couldn't go wrong for the price! Unfortunately, these do not seem to be very accurate at all. They didn't detect even a hint of hCG until late enough that I was able to get an accurate result from a Clearblue test, which at 25mIU/mL is not even half as sensitive as these are. Even after the less sensitive test came up positive, these strips barely showed a positive result! Pregnancy tests are one of the few times where 'You get what you pay for' isn't necessarily true. Lateral flow tests are fairly basic technology that are difficult to get wrong except in cases of user error or defective test units. The control line for these tests shows a lovely, vivid line, but the positive result line is so faint at >25mIU/mL that you can barely be sure it's even there — and it wasn't there even slightly in the days preceeding the positive result. This is true of multiple test units and instructions were followed to the tee, so it's unlikely user error was at play. Poor quality materials or assembly, I'd wager. These will do in a pinch if you bought a pricey brand name test and you want to verify a positive, or if you've had a few false negatives and want to cheaply repeat the tests over a few weeks, but if you need a very accurate test for pressing reasons, you might do yourself a favour and give these a miss.

Legit tests
My GP UK confirmed these are legit tests. They detected the hormone level in my urine from implantation but showed through incredibly faint lines. I did get a mixture of positives and negatives but this could have been time of the day and how dilute my urine was. I have now confirmed the pregnancy with the GP.

15 x Ultra early - 10mIU pregnancy tests
Excellent tests for the price. They're super cheap and also super accurate. I've used these a few times now and they're simple to use, have long expiry dates on them and work excellently. 5* from me all day long.

Not 100% trustworthy
I have been pregnant 3 times and have used these in my pregnancies and they've been fine, even picking up the pregnancies before my period was due. As soon as I've gotten a line I've followed up with another brand and got a more clear and obvious line, but these have done the job in alerting me to being pregnant. When I had a loss I used these to track my hcg back down. They worked a treat. I have heard negative things but never had an issue. I used these again this cycle and straight away I got a positive line, I kept testing again and again (which is the beauty of these tests, they're cheap so if you want to test repeatedly then they're ideal) and each time I was getting a positive line, although I was having a hard time believing I was pregnant. Among these positives I was getting the odd negative here and there. Using my first morning urine I was getting negatives but faint lines by the afternoon. I switched brands and every single one was negative. I left it a few more days and I was getting negatives consistently, then today another positive line. I am not pregnant, and I'm so disappointed that these tests have been inaccurate as I now can never trust them again as I used to. What I will say is this. If you want cheap pregnancy tests that can, and in my experience will, detect hcg, and you want to test many times without the expense, especially if you're tracking hcg up or down, then these are great. But if you get a second line, take it with a pinch of salt and double check it with another brand. If you feel that seeing a positive result and then later finding out you're not pregnant is going to be damaging to you or your mental health, then avoid these tests because there's a chance (and I believe it's small because I've used these for 5 years with no problems until now) that you might get a false result. In terms of ease of use, I rate them highly, you can take a few tests in your handbag, if you're travelling then it's great as they're so tiny and discreet. Easy to dip for 15 seconds and results appear very quickly and positive results are clear.

Does the job! Just be patient🤞🏽
These pregnancy strips work in the same way as the shop bought ones except they are literally just a strip not all the extra plastic. The only difference in the way you use them is that you wee into a pot first and then dip the strip in, instead of weeing directly onto a plastic stick. These strips have very clear instructions on how to use and clearly explains what a positive/negative result looks like. Mine tested positive first time with two very clear lines! .. at the time I was already 8-9 weeks. I was pleased I could test as many times as I wanted as I had 15 strips for only a few pounds! Such good value for money compared to shop bought £10-£20 a go! I think what a lot of the negative comments refer to is that they are not as accurate/sensitive reading results before a period is due .. I purchased again a few years later and have used these recently for another pregnancy and tested many times over the last few months.. (again you don’t mind how many times you test for such good value) normally I have had just one clear line and absolutely nothing else.. then a period a few days later so that confirmed that!! .. Two weeks ago I tested just before I was due on and got a negative result.. a few days later still no period so I tested again and got a VERY faint line on the ‘test line’ but after a few minutes.. Next day, another test and an ever so slightly stronger line.. I’ve waited another week so it’s been nearly 7 weeks since my last period and tested this morning to get an instant result of two dark lines. (See pic) In all fairness it depends on each woman’s HCG level.. and how far along you are.. everyone is different. Good luck.

Very disappointed, NOT 10mUI!
These were extremely disappointing! I only give it one star because it had a lot of dye. Other than that it's horrible. I had good hope for them because the control line was REALLY dark unlike a previous batch of tests I bought on amazon where the control line looked like a faint positive. But as it turns out, these tests are horrible. They say 10mUI on every package, which would mean you take take it 6 days earlier than regular, less sensitive tests, but that is not true at all. I saw an extremely faint line on it at 12dpo (well past the 6 days before), and decided to test again the next day because I thought I was imagining it and after a few minutes it disappeared. So at 13dpo I see a line slightly darker but still barely noticeable. Just enough to make me realize I was not imagining it. So I decided to try 2 brands of less sensitive tests I had leftover from previous cycles. One is a 4 days before type (so less sensitive) and the other is a cheap regular test from Action. Both of these less sensitive tests gave me a much darker line. Still light obviously, but much more visible. And they did not disappear. Then today I tested again to see if the line was getting darker. Figured it would be okay to use these alleged 10mUI test again because for sure it would be getting darker. There was a barely noticeable line so I didn't even wait the full 5 minutes and tested with the 4 days earlier test (all using the same sample of urine, obviously). I got a line is much darker than yesterday, almost twice as dark. Went to check the 10mUI test again and the line is completely gone. You can't see it at all. I'm glad I had the other tests and didn't see the disappearing line before I confirmed the result with them, or I'd be really freaked out that I was no longer pregnant which would be really upsetting after trying for over2 years with not a single positive this whole time. I don't know if I got a defective batch or what, but I'm never buying tests on Amazon.uk ever again. Yes, they are extremely cheap, but twice from different sellers I had questionable tests. Had I purchased from the same place as my less sensitive tests (which also offer a 10mUI version) I would probably have gotten a positive at 10dpo or even earlier, which is the whole point of these extra sensitive tests. The ovulation tests from the same brand seem fine, even thought I never got a line exactly as dark as the control, it was close enough. But the pregnancy ones are a joke. If anyone is interested, lot number is 20151227, expiration date Dec 26, 2018. UPDATE: I'm now over 10 weeks pregnant and decided to take another one of these tests because I still had a couple left, so why not? I was expecting to get a VERY dark line because it's been weeks since my first positive. Even a crappy test would show a very dark line by now because I have been getting dark lines since 5 weeks. Well, the line barely changed at all from the last time I used it many weeks ago. It's only about 50% as dark as the control. It should be extremely dark by now. Something is really wrong with this test. For comparison, the ovulation version gives me an off the charts dark line. As in, as soon as it touches the urine, an extremely dark line shows up and steals most of the dye from the control line. I think it's pretty ridiculous that the ovulation test seems more reliable and sensitive as a pregnancy test than the actual pregnancy test.
