Firstly, the customer service offered by Ride & Glide is excellent - I forgot to write my helmet size in the shipping notes (for the free helmet) and before I could write a follow-up email I had a friendly staff member call me asking me what helmet size I would like and mentioning that I could pick up the scooter if I'd like since I'm local. Following that, I was kept up to date every step of the way. You can tell that the people who work here genuinely care and I will not be going anywhere else for my future electric vehicles!
Now, with regards to the dualtron mini - this is a fantastic scooter (especially for the money). I upgraded to this from a Xiaomi Mi Pro 2 and honestly, there is no comparison. I paid £600 for my Xiaomi and £684 for the dualtron (during the Halloween sale). With that I got a free helmet worth around £40-£50 and a fast charger worth around £140. Absolute bargain. The daultron has great suspension, a strong motor, fantastic build quality and of course the eye throttle / controller. Definitely a great upgrade from a Xiaomi or something like that, but I'd argue also great for a first scooter if you're a beginner. If you find it's too powerful, you can easily modify the power output, acceleration and so on using the eye controller. But, even at max power it is very easy to control but also plenty powerful.
Very fast to get up to around 20MPH and have managed to get it up to around 30MPH top speed (keep in mind I'm a particularly heavy bloke). I would not recommend riding it at its top speed for long durations because it definitely feels less stable and diminishes the range dramatically but the point is that the power is there if you want it.
The only downside to the dualtron mini is the single rear drum brake is a bit underpowered considering the speeds you can ride this scooter at. It's not a problem, but it's something to keep in mind. Take some time to learn stance / positioning on escooter's and you'll have no problem. Main thing to keep in mind is when braking, try to lean back and shift your body weight onto your back foot to help slow the scooter down.
TLDR: Ride & Glide are amazing, as is this dualtron mini and if you're looking at getting it as an upgrade to a Xiaomi (or equivalent) or as a first scooter, I'd highly recommend buying one.
