After 350km of use, I note the following:
1. If you find it at the price I bought it (330€), it is a value for money choice. It's worth the money - more than that makes it overpriced.
2. The battery never has a range of 30km, but it will easily do 18-19km at full throttle. Perhaps the 30km can be achieved in eco mode, which I never use as the scooter is annoyingly slow with this mode activated.
3. If you are careful on your routes and avoid potholes, sidewalks, rocky dirt paths, and road irregularities in general, then the scooter is 100% reliable and does not suffer at all. However, it requires delicate and careful handling to keep it trouble-free, and it would also be good to regularly check the correct tire pressure.
4. It is very convenient to store, folds easily and fits anywhere.
5. It requires many hours to charge up to 100% - around 10 hours in the household outlet that I use.
6. Its brakes are very satisfactory, as well as the front LED light which illuminates the road adequately.

Guys I bought it in July 2019 and it was a very nice experience. Powerful motor, good battery. I didn't let it drop below 90%, I put it straight for charging. After 500 km it needs a check-up. At 1000 kilometers (about a year later) the tires started to burst. One after the other with use on asphalt. I changed 10 umbrellas within two months. At 1500 my rear mudguard broke, the throttle simply burned out and the screw holding the handlebar neck in the folding mechanism fell due to vibrations. I would prefer it with suspension because it is a basic problem that they have not solved in the new version and they are not going to. Due to the vibrations, the tires burst and the screws loosen. The scooter uses lithium batteries and when the battery reaches 50%, the motor loses power and speed. I do not recommend it and do not buy it if you live somewhere with many hills, it will not take you as it should. The frame is very sturdy and withstands everything. In general, it is good but that's it, that's why three stars. I would not prefer it just because info quest does not deal with anything. Once I took it inside to change the tire because I was tired and to change it, they kept it for two weeks even though I told them I needed it for my work. Guess the price. 25€ labor and 5€ the umbrella. Why? For 10 minutes of work. Note that to change it I went and made a fuss. And if I had taken it without changing it, I would have paid them 16€. The scooter, however, has basic problems and its price has gone up a lot. But it is worth it for every first experience. IT'S NOT FOR MANY MANY!

I have had the scooter for a year and a half, I have done about 1500 km and one problem after another comes up from 500 km. The fenders break easily and are very expensive, the bell rings constantly and the tires keep bursting and changing them is very difficult. I took it to the dealership because I was too lazy to change the tire for the 7th time and they asked me for 30€ and kept it for 12 days. Screws fall off the scooter due to the lack of suspension and the battery does not last as long as it says. Not even half as long as it says. I have no objections to the brakes, they are very good and the 250w motor is powerful. It climbs hills with about a 14% slope with a person weighing 85 kg. In the end, terrible Xiaomi dealership (this applies to all brands represented by Apple, Samsung, Xiaomi, DJI except for their own), it is more cost-effective with solid tires, it does not have suspension which means it is bumpy and the rear fender moves a lot (this problem has been fixed in the new version). That's why two stars.

I have been using the scooter for 6 months, having covered almost 500km with it. So, here are my comments:

Battery/Autonomy: Perhaps one of the most important features of the scooter. I almost never managed to drain its battery, but I always charged it to full. After 500km, it still maintains its autonomy with each charge (meaning it consistently consumes the same percentage of battery for the kilometers I travel on specific routes). As for the actual autonomy, it gives me approximately 20km with one charge (I weigh 65kg) on city roads with several inclines. The advertised autonomy refers to its ECO mode, which I do not use.

Speed: From a certain battery level (50-60%) and onwards, the scooter starts to lose performance and top speed. There have been days with strong headwinds and very low battery where it struggled a lot. However, for distances up to about 10km, you won't notice any decrease in speed. Beyond that, I never use the ECO mode to always have maximum performance and greater confidence when riding on busy roads.

Vibrations: Having tried Lime scooters, there is a huge difference due to the suspension. However, vibrations are still quite intense and require attention! It does not have any suspension! A road imperfection can shake you more than expected, and a ride on cobblestones can make you dizzy.

As for the various construction issues that may arise over time:

My handlebar has not shown that gap that many describe yet. I don't know if it's just a coincidence, but I make sure to ride on routes with perfect roads and try not to rely too much on the handlebar, but more on my feet.

Also, I have not encountered the common issue with the rear fender and the cable being worn out due to vibrations. Although I fear it, after 500km of careful riding, the cable has not worn out at all.

In 500km, I have only had one flat tire (and that was on the first ride) due to my own negligence, where I passed by freshly cut weeds. I make sure to check the air frequently and, as always, be careful where I ride.

Lastly, I would recommend to those considering getting it for their underage child to think twice! It is fast enough to be dangerous, mainly for the rider themselves, but also for pedestrians. Also, if you don't have a license for motorcycles/cars, be very cautious in the beginning because you will be riding alongside other vehicles in the city and you will have to follow the rules!

Oh, and let's not forget, ALWAYS WEAR A HELMET.

It's worth every penny you spend to buy it and you make a quick return on investment! I've had it for 6 months and the conclusions I've drawn are as follows:
1) Perfect brakes (when you press the brake lever, both wheels brake, not just the rear one)
2) Super powerful acceleration for its size (after the upgrade, of course) using the m365_downG app. It goes from 27km/h to 33km/h in a straight line with much more aggression during acceleration. You can disable the speed limiter on downhill slopes. For example, mine has reached up to 39 kilometers and can go even further depending on the slope.
3) I have ridden 1444 kilometers and it hasn't suffered any damage or made any noise. (Of course, I am very careful with potholes and try to ride on good roads). I have even hit some deep potholes without any issues, despite being heavy (93 kilograms).
4) It has never let me down on any uphill. It has climbed them all without needing to get off, just at a slower pace.
5) It has many accessories that you can add to it. For example, I have added a saddle, an electronic horn, a bag, an extra rear light, a fender holder, a phone holder, a cup holder, and I have also raised the handlebars. And all of these accessories cost between 3 and 5 euros each!
6) The battery needs 0.06 cents of electricity to charge from 0% to 100% and can travel approximately 20 kilometers. So, for 100 kilometers, you only need 30 cents of electricity and nothing else. When compared to other economical vehicles that require 4-5 euros plus insurance and maintenance, etc.
7) It's simply one of the best purchases you can make for your everyday needs. It's cost-effective and unique.

I bought the scooter in September and so far I have been satisfied. I was hesitant because it was quite expensive, as I saw in the comments. My concern was that I live in a city with steep hills and I was afraid of the driving behavior of the drivers in the city. Well, I have to say that my work is 12 minutes away from my house on foot and consists of two relatively steep hills, about 50 to 60% incline. It goes a bit slower uphill and struggles a bit, but it is very easy to transport, very easy to drive, and a bit dangerous on the road and the sidewalk. The rules for this vehicle are a bit strange. I charge the battery once a week and to protect myself better, I wear a bicycle helmet and I am careful where I need to go from the road to the sidewalk, of course.

It is a new technology that we all need to understand and although some drivers are literally in their own world and believe that they own the road and should honk at anyone else who has a different vehicle and curse them because of the speed, regardless of being in the city, you should go at low speeds as there are many pedestrians crossing the streets. But despite that, both pedestrians and drivers are understanding towards this vehicle and even envy it.

I believe it's worth it. You will enjoy it more in the summer than in the winter. One negative thing I can admit is that because I use it so much, I avoid walking and it may cause me to gain a few extra pounds, but I think I can manage that part. Also, one last thing I have noticed in the comments here is that many people have their rear light cable cut. Well, when you get a scooter, you should get a good adhesive tape and put it under that cable for the rear light under the wheel, and believe me, there will be no problem.
