That's a lot of money for what it is, IMHO. It looks very much like the OE jack that comes as standard with a T6.
I use my OE jack (and a piece of timber for under it) as my emergency jack, it's all well and good carrying a trolley jack if you know you will be able to stop on good tarmac or concrete to change a wheel, but a trolley jack isn't designed for use on an unmade surface and if a tyre totally deflates suddenly it might not be possible to get onto a suitably surfaced safe place to change the wheel.
