Built solid!
4 out of 5 stars
Built solid!
I had to remove the nuts so that it can fit my device and also beware pins 1 - 5 are not on the direct opposite side, they are on the bottom row while pins 6 - 9 are on the top row on the opposite side (see the inserted image with a mirror reflection of the back). Oh and don't make the mistake I did, a gender changer is not the same as null-modem. Its useless to me but its my fault. I wish I had a null-modem.

Not much to say, needed a straight through gender-changer for a ham radio that has a male port on it so I could use a cable with a male connector. I did have to unscrew one side of the screw s so that I could connect it to the radio, but they unscrewed easily using pliers.

It's a gender changer - period. They don't make VGA 'Extension' cables so this is it. Solid manufacturing and allows VGA cable to secure to the coupling. Keep extra of these for your legacy systems. I use it for a KVM setups.

it arrived quickly, got it if work, didn't end up being used. but i have never had issues with converters like this so i won't give a bad review.

Five stars means "I love it". Well, I don't think anyone can love a DB9 gender changer. So I'll use 5 stars to mean, this product was perfect for my needs. I didn't have any issues with it.

Works great, the size is very nice. You can go and buy one of those thick long gender changers but this is a pretty small adapter that works great. No problems so far and I've been using one for over a year now. Just ordered a second. No complaints great product.

This product did not work for me. I should have done more research before buying it. I had a serial cable with a male end and a connector with a male end - so naturally I assumed a gender changer would work. However, what I actually needed was a NULL modem cable. Just do your research on what kind of device you are connecting to and whether you need a NULL modem or just a gender changer ....

Not much to say, it did what I needed it to do. Note this is not a null modem adapter, just a simple straight through gender changer.
Screws can be removed from the sides if they get in your way, or just the nuts from one side if you need male threads on one side like I did...
