Anyone made or use Hub Stands?

[Barreti]

Guys, your thoughts on this please.

Last year I got a 4-post ramp and now have the Griff in the air for winter work.
But I don't like the idea of it sitting on the tyres for long periods, and axle stands on a 4-poster get in the way a bit.

So I wondered if anyone had used hub stands, or better still actually made some.
