I had to put bluetack and cotton inside the speaker to reduce the noise. It helped quite a bit. However, when it detects an obstacle, it loses the numbers and makes a prolonged beep. Sometimes I have to take out and reinsert the speed to see the indication on the screen. (I don't know if it's the product's fault or if the connection was made incorrectly.)

It was installed relatively easily.
Decent for its price. Currently (10 days) it is functioning correctly. The speaker may possibly be too loud. It can be fixed by applying insulation tape on top.

Excellent product and very low price. You do your job with more than enough and with minimal money.

For the money you pay, it's fine. The sound intensity is too high for me and it takes a few seconds to accurately show the distance. For a new or inexperienced driver, it's okay.

The screen is placed above the internal mirror. It has great accuracy in distance and at the same time strong warning sound. I highly recommend it

Very good sensors for their price. It also has a very powerful speaker and a long enough cable to do the routing.
