With the exception of the marked items, the product's quality is described as being a bit low due to its technology.

The suction power is excellent. I am very happy with the product. Just a warning, the shipping time was long, but this wasn't the fault of the shipping company. The seller took a while to begin processing the order.

The product is not working for me, however, the seller provided a refund.

The box arrived damaged. The product itself is fine. I am pleased with it, however, the foam filters were not included, which means I can't use them on my bikes.
