In general I like it. It's lightweight (which is also a minus) and works as it should. First I would rewrite the instructions. I was momentarily surprised by what was on, or by pressing the power button, or whatever. I quickly noticed it myself. While I know parts can do double duty, using a placeholder for all three buttons added a moment of confusion. He worked pretty well. However, if you don't hold it tight, it will wobble. If you had to stop on rough ground or off-road, it would most likely fall over. What may not be important to its function? My recommendation, they need to heavily rubber both the bottom and the grip. I'm talking about heavy materials, almost like tire material. And also a pen because people might have to hold it. So that the arm / hand does not become numb. I may be wrong about the following, but the plastic seemed a bit flimsy to me. For example, one that easily becomes brittle when exposed to extreme temperatures, which can happen when stored in the trunk. I have a black car, it's 100 degrees outside, you look at these things that are kept in a hot box that heats up to 200 degrees. Next is the length of the tubing. It was RIGHT for my car. But if I had an SUV with bigger tires and was forced to stop with the plug, I'd have to stand and hold it. So if you don't adjust the length of the hose, be sure to add some rubber around the grip. Maybe the silicone will do the same, but the rubber will add weight and stabilize.
