Bionso 25-Piece Multimeter Leads Kit, Professional and Upgraded Test Leads Set with Replaceable Gold-Plated Multimeter Probes, Alligator Clips, Test Hooks and Back Probe Pins.

I purchased these leads to replace the cheap plastic ones that came with my Fluke 170 meter. After doing some research and comparing different brands on Amazon, I chose these based on reviews and the fact that the tips are gold-plated. The build quality is solid. While they aren’t as thick as the leads that come with high-end multimeters, at 3.5mm they feel durable enough. The set includes multiple gold-plated tips, though the 90-degree banana plugs that connect to the meter are not gold-plated. They worked fine with my Fluke 170, but at first they felt like they barely made contact. I ended up trimming about 3-4mm off the shrouds of the banana plugs, which made a big difference - the leads now seat fully and securely. The silicone insulation is soft and flexible, a huge improvement over the stiff plastic leads my meter originally came with. The set also includes a good variety of accessories and probe tips. My only complaint is that the alligator clips are on the small side, opening to only about 3/8”. That’s fine for most tasks, but I purchased larger clips separately to complement the set. Overall, I’m very happy with these leads and would recommend them.

This 25-piece lead kit is good quality and comes with just about everything you could need for any type of testing you can think of with a multimeter. The variety of attachments covers pretty much every scenario, from fine electronics work to heavier-duty connections. It fits my Fluke multimeter perfectly, and all the pieces feel solid and well-made. Having everything in one kit is incredibly convenient, and it’s a great value for the range of tools you get. Bottom line: High-quality kit, tons of options, and a perfect fit for my Fluke—highly recommend.

These are really nice leads. Better flexibility and feel than standard leads that come with multimeters. Even the standard fluke leads at work don’t feel better. Obviously fluke’s extra flexible silicone leads beat them, but these are great stand-ins that don’t break the bank. It’s nice to have so many options in one kit. I do wish they had a bent set of back probes, but at this price point and quality, you already get a lot for your money. Right now, I’m using them at home with my Klein multimeters, and I can say they are perfect for DIY work. I would not use them for any professional work as they do not carry a UL listing… but I’ve used them for multiple standard home projects…diagnosing parasitic draw in vehicles, diagnosing pellet stoves, checking/replacing switches and outlets, full home generator repair, continuity testing, resistance testing, EV charger installation, small electronics testing, plow limit switch diagnosis, relay/solenoid/contactor diagnosis and mapping, fixture installs, etc. They’ve seen some use, and still work fine. Remember to ALWAYS do your live dead live testing before working on equipment you think is de-energized! And stay away from capacitors that are wider than your thumb if you don’t know how to safely discharge them (50v caps=typically safe, but don’t risk it). Make sure your multimeter and leads are the correct category for your job

The versatility of adding probes, clips, test hooks, and back probe pins are nice. They came in separate plastic bags, inside a storage box. I was looking for a probe to add to options for use instead of an MP4 or Alligator Clip connection. I assembled a the 3cm long probe. I removed the shrouding on the 4mm Banna plugs and it fit. I tested a 12 Volt SUV battery and a 100 Watt Solar Panel. The Connections work. I sent the EMail for Warranty Lifetime to Bionso. Worth the money.

This is a pretty comprehensive set of probe/test leads that I think will work with any multi meter out there. I've had them for 3 years now. I'm using these on a Astro AI True RMS6000 and extech meters. Mostly for automotive work. The plastic parts are sturdy, but I think the metal parts could be a little beefier as they are kinda on the delicate side of things. All in all, I don't want to be without them. When you need it, you need it.

One of the most important features I look for in test leads is the flexibility of the wire. Silicone is the best material for flexibility in this area. I am looking for well-cooked spaghetti noodle-type flexibility, with zero memory. The reason for this is because it is quite annoying to have stiff leads that will not conform to the job at hand, getting tangled, in the way, or perhaps knocking over other components as you use the leads. I have experience with Fluke silicone leads, which can be considered the gold standard, as they are exactly like the spaghetti I mentioned earlier. The Fluke leads have no memory at all and are quite limp, as required, but, if you look, you will see that Fluke is quite proud of their leads, and out of my budget at this time. These silicone leads are not quite as flexible/limp as Fluke leads, but they are close, having almost no memory at a fraction of the cost of Fluke leads. I can deal with that. You want to stay away from leads that are vinyl or other material, as they have a lot of memory in them. The resistance of the leads is .1 ohms, and that is expected. I also like the fact that these leads have a banana connector at both ends, a feature that makes working with them much easier, as I don't have the thread on alligator clips or other ends, I can just pull off the stick ends and put on whatever type end I need at the moment. Additionally, if you have the necessary banana connectors, you can use these leads in conjunction with another set of leads to extend your reach, if that becomes necessary. I have not yet tried all of the accessory ends that came with this set yet, though I did change the slick tips to the smaller ones included in the kit, but am impressed that so many came with it for the price. I will update once I check out the other types of ends. The smaller tips can plug into a breadboard hole with a little resistance. This is very helpful to me when probing around a circuit I am working on. I do wish that Bionso offered replacement tips, though. I got a set for a friend and while he likes them, he tends to put a lot of pressure on the tips, to get a good connection, and bends them.

Awesome assortment of tools for any project.

Instead of digging around for the right attachment, I’ve got it all in one kit: Standard probe tips Alligator clips Test hooks Back-probe pins It sounds simple, but having it organized saves me a ton of time. Back-Probing Is a Huge Upgrade The back-probe pins are probably what I use the most. Being able to test connectors without damaging them is a game changer—especially for automotive work and tight electronics. Swappable Tips Actually Feel Solid I was a little skeptical about interchangeable tips, but they lock in well and don’t feel loose. The gold-plated tips also seem to make consistent contact, which helps avoid flaky readings.

I needed a needle probe to fit inside a breadboard and it would have cost about $30 on Amazon for the probe tips and a cable that supports the plug. For just $20 more, I got this whole kit jam packed full of connectors that frankly I didn't know existed - and I couldn't be happier! Firstly, the quality of this kit is shockingly good. If I was gifted this, I'd easily expect it to have cost over $200. The cable is of good quality, the banana connectors are thick and solid, and the rubber coating on the cable is flexible with a soft feeling. I've used all of the probe connectors and they worked right out of the box, first time. The alligator clips are 10x better quality than anything you'll find from other sellers on Amazon, this was a real value add. The needle probes have been put under some decent stress but they're flexible and haven't bent/snapped. The probes appear gold plated to the eye but I don't have a test for metallurgy. Though, I can say the probes that came with my Klein Tools multimeter are not as sensitive as the ones in this kit, a continuance test produces solid tone when any part of the probes touch while the Klein Tools only work with the very tip (note: the only probes from this kit that require tip connection is the needle probes). It's easy to swap out probes by removing the guard and twisting the new ones in, there are instructions provided. The case is really nice, too - it's clear plastic with plenty of space for extra things, a secure snap-shut clip, and the plastic feels soft which makes me think it's quality. I very, very rarely come across a product that surprised me with fantastic bang for your buck and this is one of them. We tend to see a lot of very poorly made items flooding the market because they're cheap but this kit will keep me going for a long, long time. If you're on the fence, I seriously think you won't regret it once it arrives.

For decades, I would periodically mutilate a pair of safety pins and wrap them around my meter probes...no more! Needle probes work well, allowing me to check surface-mount parts and even giving me some hope of troubleshooting on a board with heavy conformal coating that shrugs off conventional blunt probes. Alligator clamps very useful instead of adding a jumper lead and hoping it doesn't fall off the meter probe. After many weeks of use, all the plugs and connections remain solid - I use this set with my Fluke 115 and backup Extech MN35, but it does not fit my $5 E-bay meter. No issues, leads are quite flexible in use and appear to be a reasonable gauge size for the current rating. I would have found these a solid choice back in my steel mill maintenance days and for home/hobby bench electronics they are a luxury I've earned after so many years of struggling with 3-rate improvisations.
