That looks like a nice package. I bought a similar and smaller slider hi-lift adaptor from some guy on YotaTech years ago. Mine is a half moon shape so it fits a slider perfectly. But, you do need to carry around a small piece of rubber to put in there or it will slip out on you. That has heppened to me twice.
I was actually contemplating the wheel lift adaptor that I believe ARB makes as a x-mas gift last week but passed. I can't think of many situations I would use it. You can't use it to change a tire with, so it would only be used to free a stuck axle. Yet, the high lift on the slider or winch could accomplish the same thing. Granted not as efficiently.
