WIROJ BlueSunshine Digital Camera Bike Handlebar Mount 1/4" Screw Clamp Bracket Tripod Holder Clamp for DSLR SLR Camera

Shook whenever using it. Nothing felt secure. Tried 2 speakers in it, and one (maybe not 100% the fault of this product) fell off because the inside price of the speaker loosened. I can't help think it was because it was shaking so much that I kept trying to tighten. I have moved from that in the second speaker and it hasn't stripped, but it still does shake alot on the stem of the fastner (i just dont try to tighten it).

I bought these to mount Bluetooth speakers to my atvs. They work great. We have had one break under very heavy usage but I believe it may have been on the mount incorrectly.
