    Hooks up quickly to a bread board. Works with WIn7. Cheap. What more can I say. Works great.

    Easy to use and compatible with Win8, good replace for PL2303HX

    Awful wire quality, insulation was spotty and broken, wires broke after one use. To its credit was plug and play, drivers work great with win8. Really disappointing quality of the wires though, I’d hope it was just an issue with mine but it’s not worth the money to buy another and check. To reiterate, wires came with broken insulation and the device is now broken after one use.
