It was purchased to fill air in the scooter tires, which it does in a few seconds. The battery lasts for months for this use and, even though it remains inactive in the meantime, it does not discharge. The size is very convenient so as not to take up much space under the seat. The screen is very clear even in daylight and the quality of the materials is satisfactory for the intended use. The additional nozzles are useful (e.g. for inflating a ball). There is the possibility of extending the warranty by sending the receipt via email to the company (Ksix), and regarding a question I needed to ask, I contacted them through their corporate WhatsApp account and there was an immediate response. At a price of around 45 euros, it is highly recommended!
