I used those for drum overheads until I switched to a pair that came with their own shock mounts. They did the job quite well, were easy to use, held the mics securely and offered the expected degree of isolation. I wasn't expecting much due to their inexpensive price, but I was pleasantly surprised - they just work fine, no issues at all.
PROS: reliable, quite well built, a solid product that does its job.
CONS: none at this price point.
Recommended to home or small commercial studio owners, even simply as a spare.
