If you enjoyed the first volume then you'll surely like this one. This didn't come with a tester like the first but the book is considerably larger and includes many more switches. The graphics and text look amazing. This is a really nice addition to any mech keyboard collection. Small makers like Romly are what make this community so awesome.
The second volume includes switches that are not so well known. The photos are really detailed and the data is almost impossible to find elsewhere. The English grammar is still a bit off but still much better than the previous one.
