### ⭐⭐⭐⭐⭐ easy compact solution

Just what the doctor ordered.

### ⭐⭐⭐⭐ Good value
*by C***R on January 7, 2020*

I've use quite a few of these over the last year. One if them failed on us but it was subjected to a lot of vibration. They're a good price and I like that they're narrow. Other null modems I've used are like an inch long for some reason. They're also clearly labeled as "null modems" so you can't confuse them with gender changers
