Segway Ninebot ES4 Electric Kick Scooter

UPDATE 8/30/22: IT GOT WORSE! i got a replacement, and after about 2 months of riding, it started throttling and beeping while charging... the batteries were not drawing power at the same rate, the external battery disappeared from the app and the internal was drained. when charging, it beeps until the until internal battery was charged to about 50% or got close up whatever the external was at, then the beeping would stop and they both charged together. got a SECOND REPLACEMENT, AND THEY BOTH ARE DOING THE SAME THING NOW, IN ABOUT 100 DAYS , THEY BOTH THROTTLED TO 13MPH AND WON'T CHARGE CORRECTLY, and makes the scooter useless and dangerous, you can't even just take the external battery off and use as the cheaper es2. segway solution is seems it to them and they'll take care of it... and send a replacement if they can't repair.... did I mention the replacement FAILED THE SAME WAY?? this is a KNOWN issue to segway, BUT THEY JUST KEEP SELLING THEM AT TWICE THE PRICE I PAID 2 YEARS AGO! I have 2 useless scooters and no way to commute for the MONTHS IT TAKES SEGWAY TO REPAI/REPLACE.DO NOT BUY! DO NOT BUY! DO NOT BUY! DO NOT BUY!DOOOOOO NOOOOTTTTTT BUUUYYYYYY!!!UPDATE 10/6/21: the rear fender AND brake just cracked and fell off the scooter at a red light. the lights stopped working, and the somehow the battery became disconnected? i started the repair process in JUNE and they got back to me right away and sent out a return label. unfortunately i wasn't able to pack it up for shipping (no tape) and let time slip by (thanks pandemic!), so by the time i was able to get tape about 3 weeks had passed and i wasn't sure if the label was any good anymore, so i tried to contact them... this is where everything else went to hell - they told me the label was no good and they'd send another- then, they didn't. then i decided to try chat again and i find out SEGWAY WAS MOVING FROM TEXAS TO CALIFORNIA AND WASN'T ABLE TO TAKE REPAIRS AND TO WAIT A WHILE - so i emailed to ask how long and got no response so i left it alone for 2 weeks. then i checked back in and someone had responded the next day (EYEROLL PLEASE) and now no one was responding. FINALLY someone answers my email and asks for my shipping address again, so i give it, and nothing..... so i chat again, and guess what? THEY DON'T HAVE PARTS OR REPLACEMENTS! so they have no way to tell me how long they'll have the scooter before anything can get done; so they said they'd refund the thing. great, except they sent a new label with an rma that said i could track the repair, and now no one is responding to my email asking "how long for the repair" or "am i getting the refund they said i'd get" so i'm not sending the thing to have it held hostage. WHAT A CRAP SITUATION WITH SEGWAY! i missed the ENTIRE SUMMER because of this bs. i had a lot of fun when it worked and wasn't falling apart. i alsmost killed myself in a human scorpion back in february, and it was still worth it - now it isn't anymore. the worst part is that i purchased the extended amazon warranty but it doesn't kick in until the manufacturers' warranty expires and that means letting segway ignore me for another 2 months. notice my original review also complained about customer service and i guess that's a pattern. ↓the es4 came locked at a 5.8mph speed limit in all 3 modes. customer service is a joke, they know resetting doesn't fix this problem, but they keep telling you that anyway. i get the feeling their cs is reading a manual and have no idea what they're talking about. they tend to encourage you to replace it like the next one won't have the same problem. I'm probably returning not replacing specifically because i can't risk a replacement going on the fritz after the extended warranty amazon sold me runs out because i don't trust segway ninebot customer service to be able to help after its too late to return/replace. too bad too, because i do like the scooter i just need it to do what it advertised.
