The shipping was very quick, and the quality is good.

The product is good and matches the description. The seller sent two devices, even though I only ordered one. Nice :)

The package arrived very fast. All is as it should be. I am very grateful.

The device only offers two suction levels, not the three that were mentioned. The display uses Chinese characters, and the included instructions are also only in Chinese. However, it appears to work effectively for its intended purpose.
