Love it! Smooth, fast, sharp looking.

Concerning the ticking noise, the seller is sending me parts to fix it. The seller has been very nice and friendly to deal with.

Not easy to ship, buy a ramp scooter carrier!

I like this unit because it allows me to get out and go anywhere I want without getting fatigue or in extreme pain and saves time while taking my buddy out for walks and do his business. Battery life lasts quite well before recharging and had no issues with it at all.

Love this scooter but has a few faults

Love this scooter but has a few faults. Not enough weight on front wheel. Causes wheel to spin. I added two 20 lb weights to front wheel shaft. That helps.
