The CK one may have better rubber for the cups, so maybe hold suction better... however its still a lever action so you cant restore the vacuum without undoing it.
Get two of the cheap screwfix tripple lifters, that way theres six cups holding.
Blowing £50, get this... i have actually hung from mine with it attached to a garage door.

Thanks for all the tips. I will have to get measuring and shopping. The double glazing units are aluminium framed but probably about the same weight as plastic. The glazing beads are on the outside. I wonder what the difference is between the £6.99 suction lifter and the £59.99 CK suction lifter at Screwfix.
