Paid for it. Never received. Took my money and want communicate.

I was quite disappointed with the condition of this product upon arrival. The packaging seemed slightly unsealed, and the screen was missing the proper protective film that should come with a new device. Instead, there was only the pull-tab sticker awkwardly attached directly to the screen, which makes no sense and leaves me questioning whether this product was truly new. For the price, I expect to receive a properly sealed, untouched product with full assurance it hasn’t been used before. Unfortunately, this experience left me with serious doubts about quality control and trust in the seller.

VEVOR Air Quality Monitor 8-IN-1, Professional - broke in 2 hours after I receive it, after first charge. Now it doesn't charging and when I try to start it shutdowns in two seconds. This store doesn't want to replace it or return me money. No trust any more.

Your customer service is awful.

Does not accurately detect CO2 which was my main reason for purchase. It reads atmospheric CO2 (~420ppm) successfully when outside but then stays at that level even when brought inside where CO2 should be much higher eg. 700/800ppm which other CO2 readers successfully detect. Return requested.
