I had bought 20 pieces as a precaution. It always came out negative. Eventually, when I had symptoms, I tried it and it came out positive in about 5 minutes with a strong line on the T. I confirmed it with a rapid test at the health center and with some other self-tests that I bought from the pharmacy. It is an excellent and reliable choice. I highly recommend it. For the past 10 days that it has been positive, I take the test every other day. Today it came out positive with a faint second line. Get well soon to all the affected and be patient. Have a cup of tea with honey and a little milk and communicate with your doctor.

Star test, in all predictions, at a very low price. Positive, negative exactly like PCR result. Two or three drops, a little patience and reliable result is enough, of course, if we take the sample correctly! It has been used more than 15 times and it works every time!! A lifesaver for vaccinated and unvaccinated people, and I wonder about the negative reviews too!

I see quite a few negative comments about the product and I wonder.
I have used over 20 and they were all correct and good.
I have been using them for a long time and I am very satisfied.
It diagnosed COVID-19 in my wife and son immediately.
It requires 3 drops.

In relation to what we received for free, it is bad.. It doesn't show results with 3 drops, I had to use 4 for the result line to start appearing.. It may be cheap, but I don't think it's reliable.

We bought 10 pieces, out of which 2 did not produce any results (did not color at all). I believe that a 20% failure rate is a bad result, especially when we have tried so many others that all showed indications.

I did a self test in the morning because I didn't feel very well (I didn't have a fever or anything) and it came out negative. However, as the day went on, I didn't feel well, so I did a rapid test in the afternoon and it came out positive. Immediately after, I did another self test, which also came out positive, so I consider it accurate in measurement.

I had ordered 30 pieces in July, and sometimes it required 3 drops instead of 2. I ordered another 20 pieces in September, and I haven't encountered this issue anymore, everything has worked with 2 drops. Also, I haven't found any box missing any material.

Edit: On the 4th day of symptom appearance, I took a test and the line came out intense red.

On the 7th day, it continues to show positive, but the line is very faint, so I understand that the higher viral load you have, the more intense the line appears.

Some of the tests produce a faint, suspicious line in the detection line of the virus that might concern you for a moment. But overall, it is reliable.

2 out of 3 did not show results. The one that did show was so faint that I wasn't sure and used another brand

In a positive case of coronavirus, I did 3 tests on my son. 2 of them were for school and 1 was from the company. Only the latter showed that the child does not have the virus. We did a molecular test the next day and it was positive as usual. For me, it is completely unreliable.

Out of the 4 tests, 2 didn't even produce results. One of them, in fact, didn't have all the "components" inside, so it was thrown away immediately.

I bought 15 tests because they had good reviews here....except that 2 drops didn't work, it needed 3....I did all 15 in one day!! I almost went crazy, I bought them to have them, I got the first positive result...I got the second and third positive results, I did the rest, one negative, one positive...in the end, I had nothing, it was a mistake....15 tests for 4 euros each, tremendous damage....no, no way...saliva is better

In the two, one was a fail, the sample did not go up on the cassette.

UPDATE: In the 3rd one, there wasn't even the reactive liquid.

3 out of 3 tests I did, the solution did not rise at all. It said 2 drops and in the end it needed 3 drops like all the other tests. Big fail.

I am fully vaccinated and have recovered from the virus 8 months ago. I went on vacation following all the measures and upon returning, I took a test, just as a precaution. With 2 drops, it didn't work, with 3 it started to progress. After a few minutes, I see a faint line on the T. Of course, I freaked out. The instructions said that even with a faint line, it is considered positive. Immediately, I bought another one from a different company and also did a rapid test at the Municipality. Both were negative. Of course, I will not buy it again.

Sometimes you may need to drop three drops instead of two, as it says, but otherwise it is good for its price. Now, as for how reliable it can be, I want to believe that in general, all products of its kind are more or less the same

The best test I have used so far and at an excellent price. It has by far the best build quality, and this is evident in all its parts. Very convenient that the liquid is already in the ampoule that the sample goes into. As for the indications, it is flawless in positive and negative results (cross-checked with a Rapid test). Very fast and clear.

I bought a pack of ten. I follow the instructions to the letter, but there is always a problem. With two drops, the liquid does not flow into the cassette to see if it is valid or positive. As soon as you add a third drop, it works fine. I spoke with the representative in the Netherlands and with the company in China, and they insist that it is two drops.

First of all, I have to say that I have never been positive, so I don't know its reliability in detecting positives because all my tests are negative.
I imagine it will be (reliable).
There are some details that make it user-friendly and recommended, such as the fact that the container with the liquid is pre-sealed and you don't need to fill the empty container with liquid from another container. This is very convenient.
As mentioned by others correctly, it will work better with 3 drops and not two.
Also, it would be good for the company that distributes them to pay attention to the packaging because something is always missing. I deduct one star for this.
