Wire Terminal Crimping Tool Kit, Qibaok Ratcheting Wire Crimper AWG 22-16(0.5-1.5mm²) with 500PCS Female Male Spade Connectors & Bullet Connectors Terminals

This crimper by itself was worth the purchase. The crimps themselves are excellent.

Very solid tool, with light duty connectors. They do work very well even if they are thin. This likely isn't the best if you'll be continually disabling the contacts but works great for a permanent install. I used this to cleanly install my tail lights on a motorcycle.

The biggest frustration I had with this purchase is that the box partitions do not come up to the lid, and so all the connectors got mixed up during shipping. I got them sorted, but if I ever drop the box or it just gets turned on edge, I'll have to do it again - next time I'll make sure I get color coded ones. Beyond that, I think it's a reasonable price for a light use tool and a ton of connectors. It does feel like the tool and connectors are not quite a proper match, to get a nice clean crimp I had to start the bend on the connector, then insert the wire, then put it in the tool and crimp it. The result was nice and solid, I made the repairs I needed to, and I think they'll last - it was just harder than expected from a specialty tool. If I had a lot of these to do, I might look at other products.

I have a box full of crimpers for the squish-type spade and bullet connectors kits I've gotten over the years. This was the first I have seen that handled crimping down the "ears" at the back of the connector to hold the wire into place. A few practice runs and I was off making tightly-held in place spade connections that didn't pull out when I was trying to disconnect the male and female spade connectors. I needed to troubleshoot a relay wiring issue and this kit had the narrow male and female spade connectors that let me add jumpers wires for the relay to let me test the voltages.

Good product, crimping tool ok, horrible, cheap plastic storage organizer. Parts are mixed already before use, worthless.

Great tool I use it all the time

They've really hit a home run with this kit - it's affordable and has a nice assortment of tiny bits in there to get you over your wiring project hurdle successfully - mine was installing and wiring a new potentiometer in my laser engraver. With very little practice, and also watching a quick and random instructional video I found online, I was wiring and crimping away like a madman, effectively producing a neat and tidy installation that I can show off with pride. I recommend this kit without hesitation based on my personal hands-on experience with using it. Worth every penny!

As another reviewer noted, the box doesn't prevent the connectors and boots from mixing because there's no interference fit between the separators and the lid. I too had to sort them all when I got them. There's no clear link between which connectors go with which boots. As depicted in the description photos is not correct. The measurements in the description are also not correct and don't match what's shown on the top of the box. I primarily got this kit to make adapters so that I can connect LED turn signals (which use 3.5mm terminals) to the wiring harness in my motorcycle (which has 3.9mm connectors). I put the 11.5mm boots on the 3.9mm male side and the 24mm boots on the 3.5mm female side which seems to work OK. As far as crimping, if you look at the die, there's a wider side and a narrower side. The narrower side crimps the bare wire, while the slightly wider side crimps the insulation. Put the connector in with the insulation end (where you insert the wire) slightly protruding from the face of the crimper (on the opposite side from the one with the 0.5 - 1.5 markings). If you put it flush, it will mess up the crimp on the bare wire side, and it will feel harder to crimp. If you let the end of the connector stick out just a little, you'll get a smooth feel to the crimp and the right amount of crimp on each part of the wire.
