I had my hydragas spheres replaced a couple of weeks ago in my 2001 freestyle F by Ian and Dawn Kennedy, they came to my house in their MG EV very weird to see but not hear then arrive on my drive, they were there for about 3 hours, removed my old spheres which were still usable but obviously lacking nitrogen due to leakage over the last 20 years, replaced with recharged spheres, I have to admit I was sceptical at first what the difference would be but after a test drive I was amazed at the difference, not enormous difference to handling but less bumping and jarring and smoother ride so definitely recommended.
