Pros:
Does the job nicely. Great to have a version with a wider slot for the lower strings so that the strings fit in the slot properly without having to bend the jaws like you have to with so many other cheaper products. These are the correct size for a 4/4 violin with a traditional ebony tailpiece. 3 of these plus the other version for the E string make up a tidy matching set.
Cons:
None
