I purchased my first (and only) scooter in July 2020.
Having researched many different types I settled on a Motion Healthcare Alumina  because it was the lightest weight scooter I could find that also suited our car at the time.
I visited several shops who allowed me to try and lift a scooter into my boot, to check whether it fit and that it was not too heavy for me.
The battery life is superb ( 2.5 years later we are still using the same battery from initial purchase), It displays 4 coloured dots to indicate remaining charge. We tend to charge it overnight for several reasons: when one dot is greyed out, if we have used it for a long journey or if it hasn’t been charged after several days of use. To date we have had no charging issues and only once (after forgetting to charge over night ) did it reduce to one  remaining dot on a short walk and we turned back!
The length of time the battery lasts is reduced if our walk involves any significant inclines.
I chose to remove the arm rests - it was a personal choice and I haven’t missed them.
As you can see in several of my pictures there is  space for a large cool bag under my knees, I tend not to hang bags anywhere else.
