Hello and welcome to the forum.
The good... they're cheap.
The bad... pretty well everything else. Those hard small wheels that lift the boat off the ground very little are quite unsuited to SIBs and most launch locations. They do not cope well with soft grass, sand, mud, potholes, uneven slipways etc etc... ie pretty well every circumstance you might find yourself in launching a SIB.
You really need the stainless leg with rubber tyres.
