FUELUS Air Quality Tester, Detector, Multi-Functional Formaldehyde (HCHO) / PM2.5 / PM10 / TVOC Monitor (English Version-J)

BE AWARE OF LEGIT REVIEWS MOST OF THEM ARE FAKE ACCOUNTS CREATED BY THE SELLER. Product seems to work, i go closer to a busy street and numbers increase i go indoors where i know air is fresh and the numbers decrease. be aware this product is in Chinnese, it comes with a english manual so it takes time to get use to it. However operating it is easy once u know the meaning of each menu item.

It's works great, BUT..... It would have been great if they had included clear instructions, written by someone who actually speaks English fluently. The directions were so poor I wasn't even using it correctly for several days. It was so vague and unclear, very confusing, as though it was written by someone who had a very limited understanding of how to speak English. Because of the poor instructions I had it programmed improperly for several days. I thought my air was horrible, my friend's house also. Then I tried reprogramming it again, still no success. Another day I started playing with it trying different things and on a hunch I tried something based on a guess that maybe what it sounded like they were trying to say meant something totally different, and I got lucky! Confused? I sure was. But once I finally figured out how to program it, it gave me all new readings. A 12 year old could have explained how to set it up better than their very vague attempt at instruction. Which was pretty lame!! But, it works really well once you stumble onto getting it set properly. It does seem to be very sensitive. If they get a more qualified person to write more sensible instructions, I would give it 5 stars easily.

Produces random values. One magnitude of order off versus official outdoor PM2.5 measurements.

First review ever. This is a garbage. Only give you the number randomly. This product band in China already for non accuracy .I can’t believe amazon still allowing them to sell this. Other lesson from amazon. When you buy from amazon most of they are item not been inspected for sale in the market .

I bought 2 Air Testers for my new home, this one is better, but still looks cheap and not accurate at all. The reading digits changes nearly 50% while using or disconnect from external power, and the internal battery lasts very short. The calibration function is actually not a calibration, it just reset all digits to 0 with current circumstance, I have just realized recently. However, I have no choice but relying on this poor tester. I don't know whether the other testers can be better.

Seems to keep chronic UTIs in check, until it doesn't. I'm using fewer -- but not zero -- antibiotics since starting D-Mannose powder. This particular bag seems to be the best way to get the powder in quantity. Using about a teaspoon in the morning, and again before bed. Take it with my vitamins. Got a roaring UTI anyway, but I could tell the powder kept it from flaring up as quickly as it would have in the past.

Got these boots yesterday. At first, when I put them on, the back of the heel area felt too tight (like it was squeesing my foot), and I was worried they would be uncomfortable. I decided to try wearing them anyway, and have been wearing them all day., After an hour or so, they already feel worn in, and I love them. I did put insoles in them, as recommended in other reviews. I think they are going to be my new favorite shoes.

I absolutely love the scent and it lasts a long time. Worth every penny.
