Well, I have the 60mm version. I have it for 7 months and I have done 600km.
Positive:
1. The construction has nothing to do with Chinese brands like Xiaomi, etc.
2. Very good stability.
3. The suspensions are incredible, absorbing vibrations very well.
4. The top speed is great, rarely do I go over 75, usually I ride at 45-50.
5. The battery life depends on your settings. It has a very good system for regenerating power during braking.
6. The brakes are very good, although the ABS is not the best, but the noise doesn't bother me, that's just how ABS works.

Negative:
1. The screws from the deck need to be tightened every week, they make noise.
2. The tires it comes with are the first thing you should change, they are bad. I fell once and had over 2400km on Xiaomi tires, so it's not like I didn't have experience.
3. It doesn't have the best waterproofing, so when it rains, I wouldn't ride it. It says so in the manual, but if the road is wet, it's not a problem, just be careful when braking.

In the end, it's a very good tool. I got it instead of an electric bike because you can take it with you in the car trunk or leave it at home and not worry about it being stolen. The suspensions are necessary in Greece due to the bad roads. I now go everywhere with the scooter, no parking needed, you can take it with you or lock it somewhere with a good lock. It's not a toy, it's a tool. With 40km/h you can knock someone out, imagine going at 75. It actually requires a license.

Update 1 year later:
After 1900+ km and daily use, I can say that I solved some of the problems I mentioned earlier.
Regarding the deck noise:
- I solved the deck noise issue with washers that come with other screws. If you use W40 Teflon lubricant, they will never make noise again.
I had an issue with the handlebar making noise after a while.
- The issue was inside the handlebar at the bottom where there was friction from the factory construction. For the solution, you unscrew the handlebar at the bottom where there are 2 screws, clean the friction marks, apply W40 Teflon lubricant, screw it back on, and the noise is gone.
There were noises in the front and rear suspensions.
- The solution is once again W40, either Teflon or white grease.
As for the brakes, they are fine, at some point you will need to adjust or clean the brake pads and discs if they squeak.
- An easy process that takes about 30 minutes, it's not a big deal.

No issues have occurred with the scooter so far, everything works perfectly except for the problems I solved. It generally requires some light maintenance every 4 months, which is reasonable.

I should mention that you can get an extra charger to reduce charging time by half or get a fast charger that reduces charging time to one-third, but the faster it charges, the sooner the battery will need replacement. (You can also use the fast charger with a regular one for even faster charging, but if you use 3 chargers, the battery will catch fire, so don't do it. Also, if you use the large charger with the small one, always be close as there is a risk of overheating and fire.)

Update 2 years later (the last one):
After 5800+ km.
At 5000 km, I changed the screw under the handlebar and also replaced the QR clamp that holds the handlebar. I put a double one because I had already changed the screw twice and the handlebar was moving too much.
În general, singurul aspect negativ este cadru după multe kilometri în suspensia din spate, metalul cadrului care se prinde de suspensie se uzură și roata se ridică ușor în gropi și nu se poate face nimic în acest sens decât dacă faceți vreo invenție. Deoarece suspensia din față este într-o construcție metalică robustă, în timp ce cea din spate nu este, în comparație cu modelele mai scumpe (eagle și spider au această problemă, dar pentru cele mai ieftine nu o discut).

În general, merită banii, nu regret că l-am cumpărat, economisesc mult timp și este mult mai sigur și mai robust, nu are nicio legătură cu xiaomi pro pe care l-am avut înainte (am avut peste 2400 de kilometri pe xiaomi).
