Not very securely packed but delivered very quickly along with my other choice items precisely in 14 days. I installed it yet I will add additional review once it once it is fitted with with my inverter which is on its way and then will know how it works.
The seller should use some bubble wrapping and a better flier to pack this very tight box which would instantly transfer any shock to the product inside which is also not very high-quality plastic.

Fast sending

I received the product but I didn’t have time to test it

The air quality monitor exceeded my expectations. Its precise measurements and functionality helped me to more consciously control the level of harmful substances in the room. The device is easily configured and provides information for taking measures to improve air quality. I recommend to everyone who values taking care of their health.

The product is bad. The sound is very bad. Very quiet and consumed via Bluetooth. For 40 euros more you can get a wall amplifier with Android 11 from the company. It’s good. It’s better to stay away from these wall amplifiers. I sent the product back.
