They work.
No complaints. These connectors seem well made and are easy to assemble. I'm using them to replace, where necessary, the original connectors on a '92 RR

Easy to use, well-made and waterproof
I used these to add accessories onto a motorcycle so they can be disconnected quickly. They were high quality, easy to use and have held up to the elements.

Good connectors.l
Used for speaker install. These worked really well. However they should really include extra contacts. I ended up soldering mine on instead of crimping.

Work with real Deutsch plug
I had to replaced a bilge pump on my boat. The old connector was a Deutsch connector and all I wanted to do was to replace the male plug. I bought these and it fit with the Deutsch female plug perfect. I didn’t have to swap out both sides.

Fantastic connectors!
These are fantastic connectors. You need to pay attention to which pieces go on the mail side and which pieces go on the female side. Just look at the pictures on Amazon and you can tell. You will need a good crimping tool or else need to solder the pins on. I have an old aircraft surplus crimping tool which worked okay.

Always dependable and never a connection issue. Rock solid performance.
I've been using these Deutsch connectors for years and you know, I've really grown to appreciate their design and function. They're very water resistant for most applications and while there is a learning curve and special tools are required to utilize these, the small investment is absolutely worth every penny. If you're using these for the first time, I would definitely recommend watching a few YouTube videos to give you a heads up as to how these work as it's a bit confusing your first time. Once you're up and running, you'll wonder why you've never used anything but these.

First of all, the people that are saying these are bad, or the locks not going in, must not know how to use the product. I ordered a set of the 4 pin connectors and used them in an install today, and everything went flawless. I have zero complaints so far. Now, I cannot comment on the longevity of the product and how well the housing will hold up, I'm not sure what it's made of, but I'm not very concerned, especially when these are a fraction of the cost of the TE brand.

Pretty straight forward, make sure you solder pins to the wires for best connections.
