How is the quality of mammoth electric car?

I am the owner of Mammoth A6 Super Edition, and I have never had any quality problems. The advertising slogan says it is 100 kilometers endurance, but the speed of 25KM/H can't reach the ideal speed at all, so let's talk about endurance after the speed limit is lifted. This car can be soft-solved in the background, with a speed of about 35 kilometers per hour. Baidu map shows that the temperature in Shanghai is 10 degrees and the cruising range is about 60 kilometers. Compared with its propaganda, it can be said to be a big discount. The driving feeling of the whole vehicle is smaller than that of the calf U 1. There is only room for feet in the middle, but there is no room for other things. There is no matching trunk at present. More suitable for girls to ride. The shock absorber is very hard. Although it is an extended shock absorber, it feels useless. Compared with my calf U 1, it can be said that there is a big gap. Another disadvantage is that the mileage display is inaccurate. For example, the vehicle shows that I can ride 50 kilometers, but I only rode 3 kilometers. According to reason, there should still be 47 kilometers, but it will show that there are still 45 kilometers to ride, so this power is problematic. This car has just come out, and many places have not been optimized. Wait for the OTA upgrade and slowly optimize its battery. With the same budget of 5,000 yuan, if there is no great demand for electricity, it is recommended to buy a calf, and reply as a car owner with both calves and mammoths.
