Review on Electop 2 Pack USB Cable with On/Off Switch - Ideal for Driving Recorder, LED Desk Lamp, USB Fan, LED Strips by Robert Chandrasekar

After ordering two packs only one worked. I was able to get a replacement from Revain customer service and now both switches work. As far as used with Roku Express, they work, just not out of the box. It displays a low power warning but works properly after about a minute. It's weird, but it works. As always, Revain's customer service has been excellent. UPDATE: So now the Switch isn't getting enough power for Roku and is stuck with a low power message all the time. The switches still work, just not for what I need. Still, it would be for other uses, just not Roku. For those wanting to use the switch for Roku use, I purchased the Seattle Sports SurviVolts Male-Female USB On/Off Electric Switch here at Revain. It works perfectly. No problems with low voltage. I highly recommend it.
