I obtained a pair of hatch struts from SGS Engineering back in 2020,
choosing the VX variant as I thought they'd be more up to the job.
They worked OK, except that they juddered a lot, were quite powerful and
started leaking, and out of the 2 year warranty period.
So I opted last week for the standard variety. However when installing them today I
found they only just held up the hatch. A slight nudge, and it would fall.
So I've returned them and ordered the VX ones again.
The difference is 670N against 830N, as marked on the strut.
