Well, they're not that bad, but definitely not for professional work. As someone who needs to use these types of tools a lot, there is a big difference between them and the CherryMax G28-G30. The quality doesn't seem bad, but as others have pointed out, it often snags when the rivet shank doesn't pop out, rather than just slipping out after use like the higher-end competitors. This will require you to wiggle and wrestle a bit to push the stem out. And unlike the G28-G30, it's not exactly one push and you're done. It takes a few pinches and readjustment to push the rivet shank all the way out. The grip gets stuck midway if you're between hits on the rivet, which annoys me as it won't re-engage the stem until you pull the grip all the way out. They're good for small home projects because of the price, but if you're looking for something more professional then you'll need to spend more to get this quality and simple tool.
