This product effectively adjusts pressure and shuts off automatically, making it a worthwhile purchase at its listed price. However, it would be improved by including a storage cover.

The pump operates with some noise, but its vibrations are as expected.

The product is quite loud, but it performs its function effectively. I used it once and observed significant heat when using the 2.0 setting. While I have some concerns about the product's build quality, it's currently functioning without issues.

The product functions very loudly. The pressure line is too short and doesn't reach if the valve is on the top. The wheel rim is size 16. At 1 atmosphere of pressure, I only got 2, then 2.5 after 3 minutes after oil. I will test it further, and if it doesn't match the description, I will open a dispute.
