Review: Está muy sencillo, ya se desconecto de una terminal, la arregle soldando la pero se me perdió el botón para abrir el gancho
Review: These reminded me of old-school professional test probes that I used to have a few decades ago. I loved the micro spring hooks that made is easy to clip on to your electronics without requiring a lot of exposed leads. I really like that they are easily clipped to the pins of an ICs or leads of almost any component. The cable length is really good too, with the individual red and black leads long enough to be able to position the clips in different orientations without putting a strain on the wiring. The individual leads are really flexible and non-binding, that gives a lot of flexibility with placement, without having to fight stiff wiring. The spring clips are firm and solid; for their small surface area, the force applied to the actual contact point is very high to help ensure a solid connection so the readings will be at their best. I really like that these comes with a banana plug and it's connected with a BNC connector. This provides a lot of flexibility with how you can use these probe leads, and also what devices they are compatible with. For the banana plug, I had to look up which connector is the common. I suspected it was the one with the "tab", but was not sure. I was expecting to see the standard plus or minus. Looking it up, it is the side with the tab which plugs in to the common port. To me, it looks like the negative symbol too. I have a new oscilloscope on order, so I'm not able to fully comment on how it works with it right now, but I do plan on updating this review in the near future with more than just a few casual test. One thing I've noticed is that my new scope does not have banana plugs, but it does support BNC connectors, so I'll be able to fully utilize the cable and spring hooks, just not the banana plug. These look like these are really well made and are based upon a lot of tradition and quality. I'm looking forward to getting to use these a lot.

This works OK, most of the time the signal gets across good and clean, but sometimes there is a noisy signal if the cable is moved at the BNC side of the BNC to Banana adapter. This was seen on both the shield as well as the center conductor. I was able to fix the center conductor noise by using a probe to reduce the size of the opening in the adapters center terminal so that it fit the center pin on the cable better. This got rid of most of the noisy signal. I was not able to get rid of the loose connection on the outer shield nut of the BNC connector. This is position dependent and if the cable is rotated to just the right spot it will get loose and possibly make a noisy connection. The micro grabber clips work as expected, they are a bit delicate as they always are, but the don't get stuck when opened and close all the way when released. They are capable of grabbing onto fine wire and test points as needed. The cable is standard 75 ohm coax with nicely molded ends where it connects to the BNC or the wire leads. The coax is tight where it goes into the molded strain relief and does not move. Most of the noise issues come from the BNC to Banana adapter, it is a bit on the cheap side, the springs on the banana pins are loose and are not capable of compressing to get tight on the pins when inserted into a banana jack as the spring is a closed loop with no gap at the seam. The plug is always a bit loose when plugged into a banana jack. The looseness can be dealt with by making sure that your 3/4" spacing on your banana jack sockets is not exactly 3/4 of an inch. If it is off by a bit it forces the springs against the pins, making a better connection. The function of the cable and adapter could be improved by replacing the adapter with a better quality one. NOTE: This entire assembly does not have any sort of built in load resistor. Not in the cable and not in the adapter.
