Solid construction and heavy-duty metal mounts. I screwed mine in, so I can't vouch for the velcro, but, again, the hardware is top-notch. The cord is a good length and enables you to stealth it if you don't want to go through the trouble of hard wiring it. All ports work flawlessly and I am able to charge my iPod, cell phone and Mio Digiwalker GPS while powering my ValentineOne radar/laser detector. The fuse in the back is easily reachable if it needs to be replaced. In all honesty, the only real negative I found was semi-poor English translation in the manual that I was skimming out of sheer curiosity. Also, the plug for my GPS sometimes shakes loose, but this is only because my '86 Corolla shakes at higher speeds and probably has more to do with the plug, rather than the outlet. (The radar detector plug does not shake loose). To wrap up, I saw that someone had doubts about being able to charge and use an iPod simultaneously. I have an older iPod Video (purchased in 2005) and I can charge it with my USB charger while listening to it through my Sony head unit using an auxiliary cable. This may only work for the older iPods...I'm not sure. But with my setup, it works. Highly recommended, this. I'm very happy with my purchase and will definitely buy another one if I ever need to!
