For an economical solution, it is more than sufficient. It does what it needs to and more. I tried it on plastic and the results are excellent. I don't have an opinion on metal. It has the filers in dimensions that are usually needed. Assembly is easy and quick, while organizing and transporting it in your suitcase is convenient. The build quality could definitely be better, hence the 4 stars. Perhaps it needed better metal or a more stable handle. However, the build quality does not limit its performance. Overall, it is a good and economical solution.

I have no experience with expensive analog collections, but for its price, it does its job well. It has some construction issues, but if you don't want those, you can go for another economical category. The important thing is to always consider the price-quality ratio
