Nice product

I was a little hesitant with buying/using these in place of traditional solder, but I've been pleasantly surprised. I'll use these from time to time, but it's tough passing up a normal solder joint. One thing to note - be careful when using these in a location where there are multiple joints... It is quite easy to unsolder with a low temp material that is used in these connections with only a heat gun.

Great tool and makes rewiring fast and easy!

I should have bought these long time ago!!! I am rewiring a 1962 lincoln continental and this crimping tool works great! The feature that like the most is that you are able to adjust how tight the crimp is around the wire. It also locks as you crimp so it makes it easy to hold the connection with out it falling out or turning the wrong way. A must have if you plan on doing any automotive wiring.

Just what you need.

Very good quality. I've ordered these from many places, these are as good as more expensive brands, maybe better. The jar is nice too.

Does what it says it will, no surprises!

Perfect tool for heat shrink connections. Every crimp is tight and uniform, the ratcheting is consistent and crisp. Well worth the price. You could put Klein on the side of these and not know the difference.

Excellent product I didn't even know existed.Highly recommended.

I've been soldering, twisting, taping, wire joints for most of my life. I've used all kinds of terminal strips and other standard means of splicing wires...then I saw this.

I recently obtained a high-wattage heat gun, and this set of solder seal wire connectors. Couldn't be easier to use: just strip the ends of the two wires, insert into the appropriate sleeve (by wire size), but the ends up against each other, and intertwine the stands of the wires, set your heat gun to the highest setting, and pass the gun over and around the solder donut in the middle of the sleeve, and the heat shrink on the ends. Soon, the solder flows, and the heat shrink at the ends of the sleeve shrinks around the wire, increasing the mechanical bond.

All in all, this is a product I'd never heard of, but now can't imagine doing without.

Best crimper ever purchased.

I’ve used several wire crimpers over the years. By far, these are the best and most efficient and durable crimpers ever used.

Solid Connections

This crimping tool is heavy duty and easy to operate.

I thought I hated crimp connectors, but I guess I just hated the cheap crimping tools that I've been using for the past two decades.

Surprisingly good for the price.

using the Haisstronica HS-8327 crimping tool they hold the wire well enough that I am not worried about an electrical connection.

Anyone can use

I have many years of experience in automotive and this is by far the easiest solder tool I've yet to use.

Simply cut the wires, strip them of the plastic and joint them in the connector. I used a simple heat gun and with 30 seconds I was done.

I measured the wire before the repair and got .3 ohms after the repair I measured again and got .2 ohms

I pulled on the wires with lots of pressure and they wouldn't let go.

Great product!!!
