These are an incredible invention, I work on my car a lot so I'm constantly unhooking the negative terminal and this has made life so easy now. The build quality is good but the thickness of the metal is not the greatest, I've had no issues with power handling or conductivity but I can see if you were to tighten these way to much they will break like others have complained about in reviews, so just snug them down enough that they don't wiggle and I think they'll last forever.

Always changing battery's so the quick connects are awesom

Excelente producto cumplió mi expectativa. Facilidad para desconectar y/o conectar la batería.

If you know, you know, car terminals are the worst thing the most expensive, and when I found these universal car terminals for your battery, I completely fell in love even me as a female with long nails I was able to install them I do know a little bit about cars, but this is an easy install hands-down please get this for your car if your car terminals are loose, coming apart or corroded, because these have been the best thing I'm so happy I found them

Got it today and installed it just a few minutes ago on my 2006 Hyundai Elantra (see pic). They worked but had to reposition a plastic clamp securing the positive cable to the battery drain pan to ensure the cable reach the terminal. The terminals themselves look great once installed, but not sure about its sturdiness. When it comes to electrical connection, one must make sure they are tight, or the connection can develop heat energy. I got the hold down screws tight with the included Allen wrench but was afraid to strip the threads, even with such small wrench. The lever for clamping the terminals to the battery posts worked well in my situation. The levers are long and require enough room to turn them in order to lock the terminals to the posts. My guess is that they'll work on most cars, but depending on where the battery is located and the space around it, they may not work in all situations.

A couple of tips; 1. Make sure terminals are free of grease and clean. Use a metal brush and/or emery cloth to remove any oxidation. Same goes for the cable end that clamps down to the terminals. 2. Make sure battery terminals are as far down onto the battery posts as possible. This will ensure that if the terminal clamps were to come lose, the terminals would still stay in place. 3. You may not use all four of the included Allen screws but don't leave them lose either as vibration can make them fall out. It just takes a second to tight them or you can remove them if that's your choice. 4. If you are the type of person that always use dielectric grease, then apply it. There are many debates about it, but I've never use it and never had an issue; besides, dielectric grease is supposed to be nonconductive.
