I got the 200 fibre end glow whip kit. I'm brand new with the whip but not with flow toys.
The whip is tricky, videos online make it look much more simple than it is lol. I have gotten tangled a bunch, and not one fibre has broken on me as a result, yet. I've also dropped it and it was fine.
The light charges up pretty fast and I love the rainbow colour code for how much charge it has. Someone told me you have to long press the off switch to actually turn it all the way off, otherwise it'll go into standby, so that was helpful.
The app is a learning curve, programming your own light shows. But The pre-programmed ones are very good and there's a good mix of speeds and colour flows as standard as well as solids. I do wish I could copy colours from the pre-set combos rather than trying to find a match on the colour wheel in the app. I want a pink flow like the end of flashback (I think).
The light with the whip on it is super bright. I've never had another whip to compare to but I'd say it's brighter than my Lumo pro glow poi. Light travels well all the way to the ends of the fibre as well.
Handle is weighty but not so much as to be a problem. And the grip is good, I haven't felt it slip at all.
I also got the case, which I recommend. I don't know how you'd store this or transport it safely otherwise.
