I needed a holder which doesn't break, and found it!
When ordering, I was unsure of which size to pick for Beta-58 style mic's. Some orders and some trial and errors later, I came to this conclusion:
S: Small mics ( such as those finger-sized little condensor-mics. (Overhead type of mics)
M: For singing mics. Beta-58 and similar.
L: Not sure which type of mic it's built for... BIG ones however. A Beta-58 drowns in this one.
Of course, if I'd taken my time to check the diameter on my mics, I'd have gotten the right size straight away. Anyhow, after getting the correct sizes, I can strongly recommend these holders!
