This is a simple item that works well. A thread adapter is included so that it instantly works with 3/8" and 5/8" threads. It fits medium sized microphones.
The microphone basket material is flexible and bends with gentle force. This allows the basket to open up and receive different sizes of microphone. I would use this with medium sized microphones for greater grip - my Beyerdynamic M201 fits well but not as securely as a smaller clip. So this item is perfect for common dynamic vocal microphones.
First impressions: the top holder has a rubber base, which is very flimsy and not sturdy. Hope it does not break off after use. But the grip is good, its steady. Might be a concern for singers who hold the mic stand along with the mic and sing. Otherwise, its solid as the rubber might snap off which would make it completely useless.
I have bought this in conjunction with t.bone M85 Beta - which is a copy of Shure SM58 - it fits like a glove (you even get the black tape if you don't find green "cool", which I do) - nothing bad to say, it fits easily on a stand, has the correct clamping force to safely place the microphone - all in all, an inexpensive but an awesome purchase.
