I don't think such tools are needed at all, they look more like an annoyance than a helper. I am using wire-wrap and bare hands, tweezers, screwdrivers, toothpicks, paperclips, anything else that falls into hand if anything else than bare hands is needed.
Often found myself using one of these tools called "BGA Solder Assist", though never used them for BGA, but for generic PCB work. Couple of years ago the whole pack was $5.78 from AliExpress, free shipping.
