Impressive bit of Kit
Excellent value bit of kit with a good grip and easy to use. Perfect size and produced excellent, strong crimps. I particularly like the auto release mechanism at then end of the crimp process.

Quality, ergonomically comfortable delivery consistent performance
I use wirefy, electrical components for their high quality and consistent performance, the loss of my trusted crimping tool pushed me to purchase this OEM crimping tool, that has changeable jaws if required. Ergonomically excellent, functional and with easy use across a range of crimp sizes. Great price for the quality of manufacture and comfort. They arrived and my old crimps suddenly appeared, but these are better in terms of their functionality.

A good crimper, but room for improvement
I wanted a versatile crimping set to be able to tackle all terminal types I need when wiring up car accessories and renewing corroded connectors on my classic cars. This set fitted the bill. Crimps are good and strong, well completed and don't pull apart. Having the option to use the best jaws for the job and being confident is a real plus. I'm happy. But there is room for improvement and it's easy things too. 1. Why are the engraved numbers on the jaws not picked out in white? They are important but almost impossible to read. I did this myself, see pictures. 2. Why are not all the jaws available in the UK? I had to use Amazon USA for some, and this was needless if all jaws were made available. 3. The 9" crimper should be the one supplied with the kit. It's hardly much bigger but is a better design for larger terminal types But all in all its a good kit and I enjoy using it so that's a plus.

Good Tool. Works Great
As the title says. Works really well with zero nonsense. Feels well made and has already done quite a bit of work the past month. Stands up to a bit of rough handling been thrown about the toolbox and on site. Recommended.

Very happy
Bought these to try. We use joining connectors in Automotive wiring which are heat shrink and then heat shrink tubing over the top. One of my older crimping pliers just didnt crimp the small wires and connectors right and it meant doing them again. These have been tested today on thin wire and our small red connectors and Im very please with the result. A good crimp making a sound connection. The wire wouldnt pull out so highly recommend. If your in the Automotive industry and repair wiring these are great.

Does what it does, very well.
This Crimper does a good job with the same make heat shrink crimps, nice and easy, take your time, and pull test, before heat shrinking, I used a little heat shrink heater pen, which is more like a very large marker pen. 10/10

Very sturdy
Well made crimps, ratchet works after some adjustment, you need fairly big strong hands, I'm no weakling but still needed to use two hands to get a good crimp.

Muy buena calidad de la grimpadora. Apriete y grimpado perfecto. Graduable en la fuerza de prensado, mediante un tornillo que libera una ruedacita de trinquete que permite aumentar o disminuir la presion en la boca de la mordaza. Dentado con doble muesca para un más eficaz grimpado del terminal. Muy buena ergonómica para el apriete con la mano. Mangos en goma antideslizante. Muy robusto. Fabricado en acero y pintado en negro. Fabricado en Taiwan, para el importador/vendedor WIREFY

Perfect. Thanks

J’ai utilisé cet ensemble pour des travaux sur le circuit électrique de ma moto, et le résultat est excellent. ✅ La pince à sertir est facile à utiliser, bien conçue, avec des empreintes précises qui permettent un sertissage solide et fiable. ✅ Les cosses fournies sont de bonne qualité, et l'enrobage thermorétractable assure une protection contre l’eau et l'humidité. ✅ Il suffit de chauffer doucement (au décapeur thermique ou au briquet) pour que la gaine se rétracte parfaitement autour du câble, créant un joint propre et étanche. Très bon rapport qualité/prix, idéal pour un usage moto, voiture ou bricolage électrique en extérieur.

The reason I bought this is the ease of changing the crimping head. In conventional crimping tools that can except multiple types of crimping head, you need to unscrew the head before you can swap the head out. With this tool, you don't need to so making changing of head easy and effortless.
