Seems well made, doesn't get hot (though I haven't pulled 5 amps out of it) and all fittings seem secure. But the 12v cable really needs to be a couple foot longer. As it is, with the power supply level with the base of the mount, the cable stretches straight out to the camera on a refractor - if it was a couple of foot longer, you could run it straight up the mount then along the scope to avoid a cable hanging in space. With 5 amps of capacity, it would also be great if it was supplied with a splitter if you wanted to power your mount and your camera/dew heater etc. It's good, but with a little extra, could be really good :) Should be excellent with an ASIair.
