Flywheel eccentric resistance trainers for squats
Has anyone here ever had any experience with flywheel eccentric resistance trainers for squats / deadlifts?
I can't get a squat rack in my apartment but want to lift at home - and am tempted by an Ali Express knockoff Excentric kbox. e.g. https://www.aliexpress.com/item/1005012709993866.html
I'm fairly light (60kg) - but need to know that the resistance is going to be sufficient. In peak weight-lifting months I'm squatting a 100kg barbell - but could probably push beyond that if I could lift at home.
It's not going to break the bank - but taking a day to WFH to take the delivery (and getting shot of it if it's no good) is a faff.
Worth it?
Or not sufficient to bother with?
