The quality seems pretty good. About what you expect from bits of this "color". No problem. I'm giving it three stars because I'm really not sure if they're actually useful for a whole bunch of reasons. They're trying to be all in one, but it's a bit counterintuitive: 1 - Any type of recording you take really has to be done by hand. This might work for aluminum or whatever, but you run the risk of ruining the workpiece and/or having to enlarge the threaded hole with a power tool for this project. Pulling out the drill after using the threaded part can also lead to problems. 2 - They don't actually countersink metal holes that are cut too often. I mean, I think you do it in really high-end scenarios, but I honestly can't imagine anyone trying to use such a shortcut in really high-end scenarios. Using these to drill out a tree would really just be tap misuse in a way. So I'm not sure if a 1/4" quick release is required, although obviously it won't hurt. 4 - Given the amount of plastic and materials they used to house them, they probably would only have one bit more ergonomic. Fall with expectation of using it for long term storage. Also, there are two bits in the same compartment; I wouldn't treat my best knock that way. Not a bad idea. Not a bad product. Just not sure if there is one necessary product.
