Seat quality is poor but design and build quality is good.
I am using this knee scooter to get around my house while rehabilitating a broken ankle.  I also use it occasionally  while shopping.  It is well designed and an excellent value.<br /><br />After a few weeks of use the break cables will stretch but the are easily adjusted at the break lever, this is normal just like on a bicycle.  You need to be careful of your weight balance when using these devices.  This observation applies to all scooters  and is not specific to this brand.  If you are too weight forward when transitioning  from or to different surfaces, you are going to go over the handlebars if the front wheels hang up.<br /><br />I only have one quality issue with my scooter.  After 45 days of use the knee pad ( seat ). Has developed a long split in the cover.  It is particularly irritating as it opens up when you rest you knee on the pad grabbing you clothing or skin.  When you go to get off the scooter it holds on to your clothing. It feels like you have some glue on your knee.  I doubt this seat is going to last as long as I need the scooter for.  I will update after contacting seller to see if they stand behind their product.
