Bests & Worsts Reviews from Amazon

Other reviewers have mentioned the metal contact probe won't spring back after repeated use and unfortunately that's truth . Just one time inserting plug in a speaker/amp jack & removing it results in a loose less than secure connection, the probe crushes and doesn't spring back after the initial insertion, it's spent. If you're a perfectionist about audio you'll be sending these back. The contact crushes and will not return to original shape. I guess the majority of folks stick these together & forget about them & that's why so many people give high marks. I'm using mine wth a Yamaha RX-A660 AV tuner and a 7.2 channel Klipsch reference speaker setup & had to be very careful with my wire routings so I didn't have to remove them. For now they'll have to suffice but I'm in the market for some quality plugs that can be cycled. In the past I've used a more classic style with dual set screws or the bfa type with non conductive plastic sheath. I found some here marketed by "eastone" that don't cost an arm and a leg. If you have an application where you'll be changing your configuration and needing to plug/unplug these won't hold up. If you look close at the probe design the split/ flared section represents a smaller area compared to others where the whole probe is segmented & expanded, so maybe it's the design & not the material. The bottom line is that I'm not going to settle for an inferior product, especially when I have so much invested in every other component. I'm not here to beat up on this product but I feel compelled to join the other reviewers to let you know the shortcomings. Other than the above issue the design is adequate, the way the wire locks in is good and the body is solid metal with a grippy rubber strip, but is conductive and being a fat diameter run the risk of shorting against its neighbor. I regret buying these and have asked to return them. Unfortunately I can't recommend this product. Two stars because they do work once.
