This caddy fit my T430 perfectly!
I wanted to add a second hard drive to my laptop and this helped me do just that.
I recieved the package on time and in very good condition.
They even sent me a case for my old dvd writer/optical bay.
Very pleased with this product and would definitly recommend it to anyone in the market looking for a caddy.
