* Sturdy base, feels very secure, if you're removing it often, mark the position on the frame. The installation needs to be dead centre or seat's wheel guards will hit brakes levers/ tyre.
* It can actually cope with a heavy child, although bike balance when stationary gets hard
* Locking mechanism (plastic bar underneath for seat position) does look like the weakest link but just keep seat high enough way away from back wheel/ rack/ mudguard (by installing the base block high on the seat tube part of frame
* You can fit a normal seat post mudguard under it like Top Peak's one as long as seat high enough
* Feet loops and optional wheel guards are very needed.
* Very noisy cycling with it empty, need childs weight to keep it in position and from picking up vibrations - need MTB tyres to make it all smooth with and without child, road tyres only for perfectly smooth road/ cycle path surface.
* Even with the seat as far back as possible the adult can not really wear a back pack without hitting shild in face or getting backpack opened by the child.
* The recess space for kid's worn helmet that is a claimed feature is not really deep enough for purpose, childs helmet pushed forward by back of seat
