Anyone Tried the New Konova Slider Legs?

[MikeLem]

A couple months ago, I bought the Konova slider to use for some video projects. It's really solid, but I always had a problem with the legs not staying in place. I saw yesterday that they are offering an "update kit", which includes a new style of legs and a new stage/bearing assembly. Has anyone tried them? They look like they'd be much better. Any input would be appreciated. The kit is $60, which seems reasonable.
