Review: Not good - Did not work, cheap made
Review: Don't do it. Bought 2. Both no good. - Zero stars but I can't give zero and leave a comment. Don't buy. I purchased two and both received power on one side but wouldn't turn the power on. Past reviews speak of issues with bad connections in the device. I believe that's the issue. One of them actually had part of the switch just fall off. Zero stars. When you buy two and neither work...it feels cheap....and falls apart, big zero. They feel really cheap. I would not trust them. I made a mistake...spend the money and get something safe, from a reputable company that works. Just because a lot are sold and comments are predominantly positive...you may not be getting the full picture.
