Lovely kit, some limitations
This is a lovely lighting kit that augments an already great set. It's relatively easy to install (I found it much more straightforward than the Roller Coaster, for example). It's repetitive in a good way. And I love how hidden all of the cables are within the canopy - it's seamless.
However, there are a couple of limitations that prevent it going from 'good' to 'great':
1) I find it to be a pain to switch on the power bank. The instructions suggest leaving one of the canopy pieces partially open for ease of access, but IMO this affects the aesthetic of the LEGO set. So usually I have to spend a few minutes poking the canopy to locate the power bank, then have faff about lifting it and switching on the power bank. Sometimes I try going from underneath and switching on the power that way, meaning that I don't have to touch the canopy.
2) This is a related point, but being limited to a power bank is an issue for me. I wish I could connect this to the mains - and indeed to other fairground sets - while maintaining the playability of the set. I note that the Ferris Wheel 2.0 kit has a new rotating connecting cable - please, LMB, make this available as a DIY component! If that would solve the issue for the Carousel, it would bring this up to 5 stars.
But overall I'm satisfied with the kit - it's just not perfect.
