As the title says, these are the smallest of these retractable cables I've found and much higher quality than most others I've tried. The only ones I found there had better build quality were much larger in size. I've purchased about 25 of these and haven't had any issues.
PROS: small, good quality, cheap
CONS: they wen't out of stock once when I needed more, but no issues with the actual product.
Like others, it turns out, I was a little concerned that this really.... REALLY.....skinny cable would slow down my connections, but I see zero evidence of that over this short of a distance. The obvious advantage being that it's so flexible that it can be used for very short runs with one or more sharp turns without any concern about shorting it out, as I was with my 6" and 12" patch cables. It uses a ratchet system that locks-on every 3" or so, but then releases when you extend the cables again. Very nifty, and highly recommended. Especially at this remarkably modest price!
PROS: Tidies-up your installation, very flexible, nicely made, modestly priced, great service.
