I've purchased the Rode VXLR to use it with my Rode Filmmaker Kit lav mic system. The filmmaker kit using the small 3,5mm stereo jack so in order to plug the TX (receiver) in my camera XLR ports I needed an adapter. I got this one from Rode and it does it's job perfectly. Fits nicely and locks with the 3,5mm jack to minimize unwanted disconnecting. I've had no problems whatsoever with this adapter. It's build quality is great. Price is awesome so I am recommending this one!
