Haynes Online Manuals - Any good?

[Fastpedeller]

Over the years I've found Haynes manuals to be a reasonable guide and certainly better than nothing - more recent ones not as good as 40 years ago! Has anyone experience of the Haynes online manuals? I have two Ka+ (2016 on or mk3 - the 5door car) to maintain and about due a new timing belt.
TIA
