I bought on and find it lacking. Firstly, there is a clamping device to secure the bottom bracket to the little cradle it sits in. /The design requires that your bicycle have no center mounted kick stand! The clamp for the down tube is feeble. It also doesn't adjust for different frame geometries. it is easy to knock the bottom bracket out of the cradle without the securing hook- not vey stable. For the $40 they sell for, one could buy lumber and Saw Horse brackets and devise a cheaper, steadier stand., or hang a older style trunk bike carrier (Yard sale find almost everywhere) onto a saw horse and also have a sturdier stand.
