Bullet Butt Connectors, Sopoby 100pcs Assorted Insulated Female & Male Crimp Wire Terminals Brass, 22-16 AWG, 5 Colors

They are of good quality. I use them to fit on equipment that comes with one connector already installed. The kit allowed me to connect my machines wiring to the new equipment's connector.

I bought an Android Auto car system but wanted to be able to connect and disconnect it quickly to move from car to desktop. I purchased these Bullet Chimps and they did the job nicely. I had read other product reviews about how some are thin and not very weel made so I got these and they are sturdy. The connection in the car is perfect - no high electrical noise through my stereo as I drive down the road so the insulation is solid. I've popped these connectors numerous times now to bench my car radio for firmware updates and playing around and they are still solid.Crimping 101 - Strip wire, hold connector in crimp tool, then twist in wire and press down. Crimping 102 - GET THE RIGHT TOOLS. These connectors and most importantly a good crimper (like: IRWIN VISE-GRIP Forged Crimper, 10", 2078310. I did use those crimp kits that come with an included - very thin crimper. Those skinny crimpers are just not the same as a thicker tool to make sure your crimp is solid.

Can't think of any cons. Good product, priced fair... if I need more, I'll definitely order again.

Variety of Colors made it easy to keep track of interconnects on my project.

Good selection of connector colors,good quality and great price. Wiring up a motorcycle harness ,I needed connectors for the headlight and taillight. These connectors fit what I needed. They will also work on cars and trucks. There are plenty of them for me to use now and have some for spares. Box is small and good quality so it wont take up a lot of space and is durable and wont break like hard plastic cases. I am pleased with my purchase and glad someone is offering this product.

Saw a low review about them all being the same size, guys read! The 3rd bullet in the description says they are all the same size.... anywho, they have a snug fit which i prefer and my exaust fan can now be easily disconnected for yearly cleaning. Would buy again.

These connectors are a case of you get what you pay for. I ordered 4 boxes of these connectors for easier quick-connect of LED channels. After using over 100 pairs of these connectors, here are a few things to know:-If you want a consistent connection, use at least 18 AWG wire. Thinner wires seem to work, but are a lot more hit-or-miss. That said, you can strip off more of a thinner wire and fold it over itself once or twice and twist it together to make a better connection if needed-The orientation of the connectors in the crimping tool will make a difference in the consistency of the connection and the ease of connecting the butts together. For best results, make sure that the seam of the internal metal of the connector (male or female) is perpendicular to the jaws-The connectors don't all easily slot into each other because of lax tolerances in manufacturing. Some will slot in like butter, others will take considerable force to push into each other. I strongly recommend testing the connection between male and female before crimping wires in. Play mix and match to get as many good combos as possibleAt the end of the day, it is still a better deal to me to buy these cheap connectors and have to deal with a bit of headache than to spend 5-20x more on 'quality' connectors that effectively do the same thing.

Works, but cheaply made . When crimped, plastic cracks around connectors.
