Pros: Cheaper than any lenovo charger, including 45w slim tip. works great with my t450s ultra dock

Cons: would be too big for travel purposes, my 45w charger that came with t450s is much smaller

Pros: Cheapest around. White (didn't match my coloring, but a nice looking cable none the less) very nice packaging works at 2560x1440 from a thinkpad t450s with no issues.

Cons: white didn't match my color scheme (looks better than black cable, but my whole setup is black!) the packaging says the support of the cable is limited, my 2560x1440 27" 60hz seemed to push past it fine.

Overall Review: no point buying something else if you need a cheap cable for 1440p monitors. works fine, good length, solid product. warranty terms are great!
