I've had this for years now and it produces perfect mash (never used it for anything else). I don't have a problem with refilling the hopper as my children fight over getting their turn to squeeze the handles! Anyway, if it took any more potatoes I reckon we'd either struggle to squeeze it. Not had a problem removing the inner sleeve because I do this before the mash dries out. Dishwasher cleans it well though I lay it in carefully to avoid water gathering in handles. The bit of mash that escapes over the pressing plate hasn't bothered us. Thinking about buying another for our caravan!
