Don’t feed the troll 🤣
Some people form their views of devices based on the need to argue, when they have never used it.
No point trying to explain: they will always bring up some whataboutery to deflect the opposing, fact-based reasoned view.
As per
@Mike_P above, “there does not seem to be a group saying they have one and find it pointless.”
It is a daft price, so it it entirely normal that most people don’t have one. That £50 reduction was spectacular: although price runner shows it available for £129. What you don’t have, you don’t miss, but, as I said originally, all reviews I read were by people saying they wouldn’t ride without it now.
To my mind, it is (almost) the cycling equivalent of adaptive cruise control - where it keeps the car a distance from one’s in front, even if they lower their speed. Great safety device, I wouldn’t do without it on a daily driver, but had I never had one, I would have remained perfectly happy with normal cruise control. Others who don’t have it will feel it is an unnecessary luxury, & raise concerns over it failing.
