I liked it quite a lot, it looks good quality of materials and it is very practical and versatile, since it incorporates flashlight and emergency light, it can work as powerbank... All the accessories are well stored in the device itself, so it is very compact and manageable. I have been able to inflate 20 bars each wheel with the battery in full, about 10 minutes, and there is still battery. However, the tube heats up a lot so I advise you to pause if it is going to be used longer. Keep in mind that the battery indicator is not real, it only serves to indicate that there is battery (green) or that it needs to be charged (red), but the bars are not real. I miss that it does not keep the pressure marked if it turns off, by default it marks 250 bars. Saving that, the product seems good and very useful to me, and I recommend your purchase.
